Apple Watch Ultra 4 vs Garmin Venu X1

This is a choice between two of the most expensive smartwatches sold in India, and they share more than their price: sapphire glass, titanium parts, sharp screens, built-in maps and deep health tracking. None of that will decide the purchase. What will is the phone in your pocket, whether you want a watch that works without that phone, and how thin and light you want the watch to be.

Your phone decides first

The Apple Watch Ultra 4 works only with an iPhone 11 or later running iOS 27 or later. The Garmin Venu X1 works with both iPhone and Android. If you use Android, the choice is already made. If you use an iPhone, both are open, but note one small catch on the Garmin side: its specification sheet lists text replies and viewing images from notifications as Android-only features. The Apple Watch also ties your watch to the iOS version your iPhone can run, so the watch stays useful only as long as the phone does. Neither sheet states how long software or security updates will continue, so do not assume a period for either.

Do you need the watch to work without your phone?

The Ultra 4 has 5G (RedCap) and LTE with eSIM. It can take calls, stream music and send emergency alerts when the phone is elsewhere, and it adds a siren plus Fall Detection and Crash Detection, where the Venu X1 lists incident detection. The review notes it needs a mobile plan for these connected features. The Venu X1 has no cellular version; calls work only while it is paired with a phone, and it lists incident detection with live location sharing.

This matters to swimmers, trail runners and trekkers who like to leave the phone behind, and to anyone who wants a safety net outdoors. If you always carry your phone, you will rarely notice the difference, and you would be paying for a feature, plus a monthly plan, that you do not use.

Rugged build or slim and light

This is the real physical trade-off. The Ultra 4 is a 49 mm titanium case, listed at 63 g and 12 mm thick, with 100 m water resistance, recreational diving to 40 m and MIL-STD-810H testing. The Venu X1 is 7.9 mm thick and listed at 34 g (40 g with its band), with a polymer case, titanium caseback and 5ATM swim rating. That slim shape slips under a cuff and is easier to wear through the night for sleep tracking. Both are big: the Ultra 4 is a 49 mm case that its review calls large and heavy for smaller wrists, and the Venu X1 is wide, so try either on first if your wrist is small. At 63 g against 40 g with its band, the Ultra 4 is noticeably heavier, which matters most overnight.

For pool swimming, running, rain and everyday knocks, the Venu X1's protection is enough. Diving, harsh weather and rough use are where the Ultra 4's extra protection is actually used. Garmin's sheet lists a two-year warranty. Apple's sheet states none, so check the warranty terms at purchase.

Screens: closer than the labels suggest

The Venu X1's 2-inch AMOLED sounds like a clear win. The numbers say otherwise. Its 448 × 486 screen is 330 ppi and the Ultra 4's 422 × 514 screen is 326 ppi, so sharpness is effectively equal. Display area is 1,304 mm² against 1,245 mm², a gap of about five per cent that is hard to see. Both have always-on displays. The one documented difference is that Apple claims 3,000 nits of peak brightness, while Garmin's sheet does not state a brightness figure. In bright sun, that gives the Ultra 4 a likely edge, but this is an expectation from the claim, not a measured result.

Battery: a week against a couple of days

Garmin claims up to 8 days in smartwatch mode, falling to about 2 days with the always-on display on. Apple claims up to 50 hours of normal use, and its sheet does not say whether that includes the always-on screen. The review calls two days of normal use comfortable for the Ultra 4. So if you switch the Venu X1's always-on display off, it should last noticeably longer between charges. If you leave it on, the two are close. Neither is an endurance watch for GPS use, since Garmin claims up to 16 hours and Apple up to 18 hours of workout tracking. Both brands claim a quick recharge of about 45 minutes: Apple says the Ultra 4 reaches 80% in that time, and Garmin lists a full charge in 45 minutes. Neither sheet lists a power adapter in the box, so budget for one if you do not own a suitable USB charger.

Health tracking or training depth

Both cover heart rate, blood oxygen, skin temperature, sleep and women's health. The Ultra 4 adds an ECG app and sleep apnoea notifications. The Venu X1 lists a breathing-variations feature but no ECG. Both track running power and HRV. The Venu X1 adds Garmin's training readiness, Body Battery, coaching plans and preloaded maps for over 43,000 golf courses, which Apple's sheet does not list. Choose the Ultra 4 if heart-rhythm checks matter. Choose the Venu X1 if you follow a structured running or cycling plan. Casual users will not notice the gap.

Which one should you buy?

Choose the Apple Watch Ultra 4 if you have an iPhone and want one watch that handles diving, rough conditions, phone-free calls and ECG. It is the only one of the two that does these things. It also has twice the storage, 64 GB against 32 GB.

Choose the Garmin Venu X1 if you want a large, sharp screen in a thin, light watch that works with iPhone or Android, with stronger training tools, longer battery between charges if you keep the always-on display off, and a stated two-year warranty.

The Ultra 4 costs somewhat more, and the Titanium Milanese Loop version costs considerably more. That premium is justified only if you will use cellular, diving depth or the tougher case. Otherwise the Venu X1 offers a similar screen and, with the always-on display off, more battery for less, so it is the better value for most people who do not need those extras. Prices vary by shop, variant and offer, so check the product pages for current prices.
