I have an EZM 13 in very good condition that I’m looking to trade. I got the watch in November of last year, so it still has nearly all of its three year warranty left. Wore it consistently for two and a half months until I got my EZM 1.1. Now it is discontinued, so this will be a rare piece in the near future.

I tracked it over 70 days and it gained a total of 3 seconds. Bezel and dial markings are perfectly aligned, the CuSO4 capsule color is like new, and the AR on the crystal is flawless. Very few marks on the case, and they are all nearly invisible. You would never see them unless you were inspecting the watch closely. I spent $2970 for the watch w/the rubber strap + $300 for the bracelet for a total $3290, I’d give this watch a trade value of $2500. Included in the trade is full box (outer and inner) and papers, bracelet tool, spring bar tool, bracelet wrenches, standard rubber strap AND BRACELET, with all the links.

I’m mostly interested in other Sinn watches. Particularly the LE 103 Classic, 104 St Sa I B+cash, T1 B, 856 b-uhr+cash. I’ll consider other trades as well, and have a Sinn 104 W RS I could put towards a trade up, but any of the above is pretty much a guaranteed trade from me!

Thanks for looking!

since I first posted this watch I have noticed that the start/stop pusher is slow to return. It functions as needed, but you won’t be able to start and then stop it in less than a second. I looked into getting this fixed, but the watch was purchased from DE, so it would have to go to Sinn for a service, and I didn’t want to wait. Like I said, everything functions, and there is plenty of warranty if you want wear the watch and send it for a service down the road (when you are lusting over something new and won’t miss this watch for a couple weeks)
