For sale is my Sinn Frankfurt, ref 6000. This is a dressier than normal Sinn, who is more known for their bulkier divers. This watch has both a chrono function and a GMT function. The GMT is a little different in that it goes around the dial every 12 hours, instead of 24 like a typical GMT. The crown at 10 controls the inner 112 hour bezel, which allows you to track a third time zone. The case is 38.5 and very wearable. The lug width is 20 mm, and looks great on the bracelet, leather, or rubber. The bracelet fits a 7.5" wrist. Other than that, the watch is a full kit. It comes in a large wooden display case that includes the warranty card, polish cloth, loupe, extra spring bars, watch tool, and leather strap. The leather straps appears to never have been worn. The watch is in excellent condition considering it was originally purchased in 2001. There are some desk diving marks on the case and bracelet, but nothing that would not buff out if you so choose to do so. The watch is running great. I have it at -7 seconds per day on my timegrapher. Looking for $1,950 shipped in the US. Willing to trade down with cash to me. Would consider trading up, but really only looking for an Omega Broad Arrow chrono Pics and timestamp https://imgur.com/a/pOpRyTB https://imgur.com/a/8Kpl0Lt
