NDJ 19 Posted July 24, 2017 (edited) This is one of my genuine watches, a Sinn (pronounced 'Zinn') 356 Flieger, with acrylic crystal. I bought this because I wanted a pilot style chronograph but with a date function - as it happens this also has a day display. Sinn, very wisely in my opinion, went with the full suite of the Valjoux 7750's available complications. My watch actually has a Sellita SW500 clone however. From slightly fast when new, according to my WatchCheck App, it had slowed down to -5.2 sec/day, so I decided to open it up and regulate it: My 1st attempt brought it to -1.5 sec/day, and my second attempt to +0.3 sec/day - which I'm pretty satisfied with!

Foxindebox 462 Posted July 24, 2017 That's a lovely looking watch mate. I like it a lot! Share this post Link to post Share on other sites
NDJ 19 Posted July 24, 2017 Thanks! It is a lovely watch. If it has a fault it's that it is a bit too efficient and clinical in that German way (like a BMW or Mercedes). :P Share this post Link to post Share on other sites
