COLMI V72 vs V73: What Actually Differs Between These Sister Watches?

If you've been browsing the COLMI smartwatch range and found yourself hovering between the V72 and the V73, you're not alone. These two watches look almost identical in product listings, share the same AMOLED display technology, have virtually the same health tracking features, and sit within a few pounds of each other in price. So what actually differs between them? And more importantly, which one should you buy?

This guide gives you the most detailed, honest comparison of the COLMI V72 and V73 available anywhere. We cover every meaningful difference — and every area where they're identical — so you can make the right choice without second-guessing yourself.

The Short Answer

The COLMI V72 and V73 are sister watches built on the same hardware platform. The primary difference is colour availability. The V73 adds a Pink option and may include additional Gold variants not available on the V72. If you want Pink, buy the V73. If you prefer Rose Gold, buy the V72. If you're happy with Black or standard Gold, either watch will serve you identically well.

Everything else — display quality, health tracking, battery life, sports modes, app experience — is effectively the same between the two models.

The Key Difference: Colour Range

The most substantive difference between the V72 and V73 is the colour palette available. Understanding this clearly is the most important thing you can do before choosing between them.

COLMI V72 Colours

The V72 is available in:

Black — classic, versatile, suits any outfit and wrist size
Gold — warm yellow-gold tone with matching strap
Rose Gold — the soft pink-gold combination that's consistently one of COLMI's most popular colour options

The Rose Gold V72 is particularly sought after and is the primary reason many female buyers choose the V72 over the V73. The warm, soft combination of the rose gold case with the complementary strap is one of the most elegant colour executions in the COLMI budget smartwatch range.

COLMI V73 Colours

The V73 is available in:

Black — identical to V72 Black
Gold — comparable to V72 Gold, potentially with slightly different strap shade depending on production batch
Pink — the colour that no other COLMI smartwatch offers. A genuine fashion-forward pink case and strap that appeals to buyers who specifically want a feminine, bold colour statement

The Pink V73 is unique in the entire COLMI smartwatch lineup. If you want a pink smartwatch and you're looking at the COLMI range, the V73 is your only option. This exclusivity makes the V73 the clear recommendation for buyers who specifically want the pink aesthetic.

What If You Want Rose Gold vs Pink?

This is the most common buyer confusion between the two models. Rose Gold and Pink are meaningfully different aesthetics:

Rose Gold (V72): A metallic, sophisticated colour with golden undertones. Looks like premium jewellery. Subtle and professional enough for office wear.
Pink (V73): A more vibrant, fashion-forward colour statement. Clearly pink rather than metallic. More youthful and bold in appearance.

Both are beautiful in their own way, but they suit different styles and contexts. Knowing which aesthetic you prefer is the single most important decision factor between these two watches.

Display Quality: Identical AMOLED Technology

Both the V72 and V73 use AMOLED display technology, and in real-world use the display quality is indistinguishable between the two models. AMOLED (Active Matrix Organic Light-Emitting Diode) delivers:

True blacks — pixels producing black colour are completely off, creating absolute black that makes dark watch faces look stunning
Vivid, saturated colours — self-illuminating pixels produce richer colour than backlit LCD displays
High contrast — the ratio between brightest whites and truest blacks makes text crisp and data immediately readable
Good outdoor visibility — higher peak brightness and true blacks improve readability in sunlight compared to IPS alternatives

The display quality is one of the strongest arguments for choosing either the V72 or V73 over lower-priced COLMI models that use IPS LCD panels (like the C8 Max or V69). At their price points, the V72 and V73 offer visual quality that significantly exceeds most budget smartwatches.

Watch faces are customisable through the Da Fit app, with a library of downloadable options. Dark-background watch faces look particularly spectacular on the AMOLED panels of both watches — and choosing a dark face also extends battery life, since black pixels on AMOLED consume zero power.

Health Monitoring: No Difference Whatsoever

The health monitoring capability of the V72 and V73 is completely identical. Both watches provide:

Continuous Heart Rate Monitoring

Optical sensors on the back of both watches monitor your heart rate 24/7. Real-time readings are available from the watch face at any time, and trend data is stored in the Da Fit app. The accuracy, sampling frequency, and alert capabilities are the same on both models.

Blood Oxygen (SpO2) Monitoring

On-demand SpO2 measurements take approximately 30 seconds on both watches and provide equivalent accuracy. Both store results in the Da Fit app for historical review with no subscription required.

Sleep Stage Tracking

Both watches automatically detect sleep onset and track light, deep, and REM sleep stages throughout the night. Morning sleep quality scores and stage breakdowns are identical in format and accuracy between the two models.

Stress Monitoring

HRV-based stress monitoring on both watches generates equivalent stress scores throughout the day. Guided breathing exercises are accessible from the watch face on both models.

100+ Sports Modes

Both watches support the same library of 100+ sports modes, covering running, cycling, swimming (within IP68 limits), yoga, weight training, and many more. The sports tracking experience is identical.

Step Counting and Daily Activity

Pedometer accuracy, calorie estimation, and sedentary reminder features are equivalent on both watches. The Da Fit app experience for reviewing activity data is identical.

Menstrual Cycle Tracking

Both watches support menstrual cycle logging through the Da Fit app, with continuous health monitoring data providing physiological context around cycle phases.

Battery Life: Identical

Both the V72 and V73 deliver 7 to 12 days of typical battery life under standard use conditions — health monitoring active, notifications enabled, always-on display disabled. The efficiency of the AMOLED panels and Bluetooth 5.3 connection is the same on both models.

A practical battery tip that applies equally to both: choosing a dark-background watch face extends battery life measurably on AMOLED screens, since black pixels consume zero power. A watch face that's predominantly black uses noticeably less energy than a bright or colourful design, particularly if you check the time frequently throughout the day.

Charging via the magnetic cable takes approximately 1.5 hours from flat to full on both models.

Smart Features: Identical

The smart notification and connectivity features are the same on both watches:

Incoming call alerts with caller ID display
SMS, WhatsApp, email, and app notifications with message preview
Music playback control from the wrist
Weather forecast display synced from phone
Find my phone function
Alarm with vibration for silent wake-up
Remote camera shutter
Bluetooth 5.3 connection to iOS and Android

Neither the V72 nor V73 supports Bluetooth calling. For voice calling from the wrist, the COLMI P71 or P82 are the relevant alternatives. Neither watch has built-in GPS — for standalone GPS, the COLMI P82 or V76 are the appropriate choices.

Build Quality: Essentially Identical

Both watches use equivalent case construction and materials. The physical build quality — case rigidity, button response, glass protection, IP68 water resistance — is the same between the two models. The strap material and quality is equivalent, with both using soft silicone in their respective colour variants.

The slight £2 price premium of the V73 over the V72 does not reflect a build quality upgrade — it reflects the expanded colour options and specifically the uniqueness of the Pink variant, which commands a small premium for its exclusivity in the COLMI range.

Price: A Small but Noted Difference

The V72 is typically priced at approximately £33 while the V73 sits at approximately £35 — a £2 difference that is negligible for most buyers. This small premium on the V73 reflects the broader colour range and the Pink variant's unique positioning rather than any hardware difference.

In practice, the £2 price difference should not be the deciding factor in your choice. Colour preference is the only relevant deciding factor between these two watches.

Who Should Buy Each Watch

Buy the COLMI V72 if:

You want the Rose Gold colour option — this is exclusively on the V72 and is one of the most popular colour choices in the COLMI range
You want the standard Black variant and prefer to pay the marginally lower price
You want Gold and either colour option is available on both (choose based on any other minor preference)
Rose Gold metallic aesthetics suit your personal style better than vibrant pink

Buy the COLMI V73 if:

You want the Pink colour option — this is only available on the V73 in the entire COLMI smartwatch range
You're buying as a gift for someone who would love a pink smartwatch
You prefer the V73's specific Gold variant shade (minor production differences may exist between batches)
A bold, fashion-forward colour statement suits your style better than the Rose Gold metallic look

Frequently Asked Questions

Are the V72 and V73 the same watch with different colours?

Essentially yes. They share the same hardware platform, sensors, software, display technology, and sports mode library. The colour palette is the primary distinction. Any minor design refinements between production runs are secondary to the colour difference as a buyer decision factor.

Can I get Rose Gold on the V73?

Typically no — Rose Gold is the V72's distinctive colour option. The V73's unique offering is Pink. If you want Rose Gold, the V72 is the model to choose.

Is the V73 display better than the V72?

No. Both use AMOLED display technology with equivalent specifications. There is no display quality advantage to either model.

Does the V73's Pink colour affect sensor accuracy?

No. The colour of the case and strap has no effect on the optical sensor performance on either watch. Sensor accuracy is equivalent between all colour variants of both models.

Which has better battery life?

Both have identical battery life of 7 to 12 days under typical use. No difference.

Can both watches be worn swimming?

Both are IP68 rated, which covers splashes, sweat, rain, and brief submersion but is not certified for swimming. For a swimming-appropriate COLMI watch, the P76 (3ATM rated) is the correct choice.

Which is better value?

Both represent excellent value. The V72 is marginally cheaper; the V73 adds the Pink colour option. If the Pink option is irrelevant to you, the V72's slightly lower price represents marginally better value. If Pink is what you want, the V73 is the only way to get it.

How These Watches Compare to Other COLMI Models

Understanding where the V72 and V73 sit in the broader COLMI range helps contextualise the choice:

vs C8 Max/V69: Both V72 and V73 have significantly better displays (AMOLED vs IPS) at a small price premium. The visual upgrade is immediately apparent and worth the extra few pounds for most buyers.
vs P80/P81: The P80 and P81 have longer battery life (12 days) and more comprehensive sports mode support, but use IPS displays rather than AMOLED. If display quality is your priority, V72/V73 win. If battery life and sports depth are priorities, P80/P81 win.
vs i28 Ultra: The i28 Ultra has a higher-resolution AMOLED (466×466 pixels) and six colour/strap options including magnetic variants. It costs £11 more than the V73. If you want the absolute best display and magnetic strap options, the i28 Ultra is the step up. If you want AMOLED quality at the lowest possible price, the V72 or V73 are the better value choice.
vs M42: The M42 is the most elegant watch in the range with a slim profile and magnetic strap, but at a higher price. The V72/V73 offer AMOLED quality at a lower price point without the M42's design premium.

Our Final Recommendation

Buy the COLMI V72 if you want Rose Gold or Black at the lowest price for AMOLED quality in the COLMI range.

Buy the COLMI V73 if you want Pink — the only pink smartwatch in the COLMI lineup — or if you specifically prefer the V73's Gold variant.

Don't spend more than 30 seconds deciding between them once you know your colour preference. The hardware is the same. The experience is the same. The only thing that meaningfully differs is what colour you want on your wrist every day — and that's entirely a personal choice that only you can make.
