Up for sale is my Serica 6190. Only had it for about a month. I purchased straight from Serica and also optioned on the very nice (but very expensive) rubber strap and fitted end links. Those retail for $250. But it is the nicest rubber strap I’ve ever worn and the end links elevate the watch. Condition is lightly used, some superficial scratches on the high polished sections. See pictures. Keeping amazing time. It is cosc certified with 200 m water resist and extremely thin. The bonklip bracelet is amazingly comfortable. Asking $800 shipped conus. PayPal/ Venmo ff preferred. Thanks!
