For sale is my Sinn 356. The 356 is a classic Valjoux 7750 powered 38.5mm chronograph. This one was produced in 1998 with sales receipt from 2007. This is the acrylic crystal version and features Sinn’s bead blasted case and bracelet (this initial run of 356 used a brushed caseback). There are normal marks on the case and bracelet but I’d rate it as good condition (typical marks on the clasp from use). The T Swiss (tritium) dial is super rare (I’ve only ever seen one other) just starting to turn a creamy tone, but also shines very bright at night (and holds charge reasonably well). German only day wheel and brushed caseback on this. I had the watch serviced by Aaron Recksiek at Mt Olympus Clocks in Utah. Full movement and case service, new Acrylic crystal and crown from Sinn. Runs at around -3s/day on wrist (service was done in spring of 2023). Under a loupe, you can see a couple tiny black marks on the dial on the 6oclock sub register, from where the hand was popped off. It literally took me a year to notice it, but I wanted to call this out. Includes full kit, inner and outer box, warranty card, extra links for bracelet (currently sized for around 6.75” wrist). The 356 is an absolute classic, but one with Tritium dial, 7750 Movement, brushed caseback, makes this next level - way cooler than any of the new versions IMO. Grail on radar so pricing to move. $1800 plus shipping. no trades, selling within CONUS. [photos and timestamp](https://imgur.com/a/BWk1KsI)
