RZE Builds Its Own In-House Digital Module and Will Swap It Into Your UTD-8000

Digital watches usually die with their electronics. When the module gets old, the whole watch goes in a drawer, especially on a lower priced digital watch. Often, a replacement module will cost a hair less than a brand new watch, so why not go for a new watch. This is, of course, a bit wasteful and one of the reasons why some people don't like quartz/digital watches. RZE, the Singapore brand that makes lightweight titanium field and dive watches, agrees that this is wasteful, so they have a solution. And it's not a simple one, as it required them to develop their own in-house digital module. When's the last time you heard a watch brand do that? And the UDT digital watches going forward will all use this module. But what about you UDT-8000 owners? No biggie, for $100 RZE will sell you the new UTD-8080 movement to drop into your existing case. Very cool.

The case is Grade 2 titanium with RZE’s UltraHex surface treatment. It is 42mm wide with a bezel that overhangs to 43mm, 13.4mm thick, with a lug-to-lug of 49.5mm, and it weighs 51.9 grams. Water resistance is 200 meters. A sapphire crystal with Super AR coating on the inside covers the display. The launch model, the UTD-8080-ST, gets a white Cerakote finish with black accents.

The display moves to FSTN LCD, which has darker numerals and better legibility at steeper angles than the standard TN screens most digitals use. Functions now include dual time, multiple alarms, a countdown timer, a 1/100th-second stopwatch and a calendar that runs to 2099 without adjustment. The backlight is RZE’s UltraGlow.

The UTD-8000 ran on a modified existing module. The RZE-8080 is RZE’s own design, tested on the UTD platform since March 2025 for temperature extremes, shock, vibration and drops of more than 30 feet. It runs on a CR2032 cell rated for at least three years. RZE also plans to offer the module to other independent brands and microbrands, which could be extremely cool.

The UTD-8080-ST is priced at $399 and ships in November 2026. Standard UltraHex titanium versions follow in March 2027, priced at $299. The $100 swap for UTD-8000 owners will be available through service centers in the US, Canada, the UK and Singapore from January 2027, and RZE covers the shipping back to you.
