Looking for a cheaper alternative to the Apple Watch Ultra 4? It usually sells for about $799. Here are 6 cheaper swaps from $250: the Amazfit T-Rex 3 Pro is the closest match from another brand, the Apple Watch Ultra 3 is a cheaper option from Apple and the Garmin Instinct E (45mm) is the cheapest at about $250. Each one says what you give up for the lower price.
Worth it for iPhone owners who want the longest battery and toughest build in an Apple Watch: Apple rates it up to 50 hours, and TechRadar got about two and a half days with the always-on display on. It has a 49mm titanium case, a 3000-nit display, satellite messaging, and cellular as standard (Apple, TechRadar).
The Apple Watch Ultra 3 ($650) keeps the titanium case, LTE and satellite features, but is rated for 42 hours and, per TechRadar, misses the new sensors and Readiness Score. If you don't need the rugged build, the Apple Watch Series 12 ($399) gets the same new Health Sensing System in a lighter watch.

The Garmin Instinct E (45mm), at about $250 (69% less). Garmin's rugged Instinct design and tracking, with up to 16 days of battery, for less than a third of the price. The catch: Monochrome memory-in-pixel screen instead of AMOLED, and it runs Garmin's software, not Apple Watch apps.
The Amazfit T-Rex 3 Pro, at about $400 (50% less). Titanium bezel, sapphire glass, offline maps and dual-band GPS. The catch: No cellular version, and no replying to iMessages.

Apple added the S11 chip, a new Health Sensing System and a bigger battery rated up to 50 hours. The Apple Watch Ultra 3 ($650) is rated for 42 hours, and TechRadar says that without Readiness Score and the new sensors the experience is pretty close.
Apple rates it up to 50 hours of normal use and up to 84 hours in Low Power Mode. TechRadar got about two and a half days with the always-on display and sleep tracking, and about 30% back in 15 to 20 minutes of charging.
No. TechRadar notes Readiness Score is free on the new watch, unlike similar scores from Oura and WHOOP. It gives a 0 to 10 score based on your sleep and the previous day's activity.
Yes, the Samsung Galaxy Watch Ultra 2 ($699), which isn't a swap on this page because it doesn't work with iPhone. It has LTE as standard, a 5,000-nit screen and scuba dive certification, and Samsung rates its battery at 60 hours (Tom's Guide, TechRadar). Apple Watch Ultra 4 needs an iPhone.
Mainly for battery life and toughness. Apple rates the Ultra 4 at up to 50 hours, against up to 24 hours for the Apple Watch Series 12 ($399), and the Ultra has a 49mm titanium case with cellular as standard. The Series 12 gets the same new Health Sensing System in a lighter watch.
The Garmin, by a wide margin. Garmin rates the Garmin Instinct 3 AMOLED (45mm) ($349) at up to 18 days, against Apple's 50 hours for the Ultra 4. The Instinct 3 has a built-in flashlight but no touchscreen, maps or speaker, and few apps.
The Garmin Instinct E (45mm) ($250), with a monochrome screen and up to 16 days of battery. For a color screen, the Amazfit T-Rex 3 ($280) has a 1.5-inch AMOLED display at 2,000 nits and up to 27 days of battery, per Amazfit, but no flashlight.

Every swap is a product sold in the US that does the main job of the original. Close match is another brand with similar features, Same brand, cheaper is an older, smaller or renewed model from the same maker, and Budget pick is the cheapest thing that still does the job. On each page, Closest match is the close match nearest the original in price, and Lowest price is the cheapest swap. We compare published specs, retailer listings and reviews; we don't test products ourselves.
A cheaper product is cheaper for a reason. Each swap says what you give up, like weaker noise cancelling, a smaller screen or a shorter warranty, so you can decide if the savings are worth it.
Prices are typical US prices from retailer listings and price trackers, last checked October 2026. They are not live Amazon prices, which change often. When a price couldn't be confirmed, the page says “Check price on Amazon” instead of showing a number.
