For sale - July '24 purchased Sinn U50-T Hydro. Fully tegimented with both the short black and medium olive/grey canvas strap. $2,500 shipped, PPGS or as agreed. Will ship internationally at cost. This is a great example of why enthusiasts love Sinn. They took a great watch (the U1) and made it smaller (41mm!), thinner (11.8mm!), added sword hands, put in a regulated quartz (I showed ±1 over three weeks and it hits every hash mark), and filled it with oil. Rated to 5000 meters, you'll never find a depth that will kill it. You can read this watch from all angles and even underwater the visibility is amazing. There's not a mark on it and it's a strap monster. This is a [catch and release](https://www.reddit.com/r/Watchexchange/comments/1h7kzgq/wts_2024_sinn_u50_hydro_fully_tegimented_15_yrs/) for me. I purchased it to use as a dive watch - for snorkeling. That's what I love to do and this seemed like just the tool for the job (and then some!) But then my wife convinced me to get my PADI cert and, well, that was pretty cool, too. I'm a less-is-more-guy, so I'm putting this back out there and will wear a dive computer when I'm getting wet. I would consider a trade plus cash for a Garmin Mk3i, 43mm (or two of them, new, sent directly to me if you want to buy this on your credit card ¯\\\_(ツ)\_/¯ ) • Watch diameter (mm): 41.0 • Watch height (mm): 11.8 • Lug width (mm): 20 • Lug to lug (mm): 47 • Weight - head only (grams): 72 • Water resistance: 5,000 meters • Case back: Solid • Case finish: Matte • Case metal: Tegimented hardened submarine steel • Dial color: Black • Front crystal: Sapphire • Tegimented: Fully • Calibre: Ronda 715 Li • Movement: Quartz oil filled • Strap or bracelet: Strap • Manufacturer's limited warranty: 3 years, until July 2027 • Warranty service: Sinn Germany
