Hi all,

My vintage Sinn Chronograph is still for sale! There is a bit of mystery surrounding this piece as there is no reference number for this watch. I did a bit of research and found that the watch actually has a Guinand 361 case but with the Sinn dial. This would make sense because Sinn was known to contract Guinand for cases and parts. I have been able to find 4 of these watches on separate forums around the world.

As you research vintage Sinn, you’ll find that very few, if any, are alike. What I have found is that Sinn being originally a very small company, would use other large companies to assemble some of their inventory on contract, and wouldn’t pay much attention to details on crowns, hands, etc.

There are some light scratches on the case but no major dents or dings. The only thing to note condition wise is a slight indentation between 1 and 2 on the dial. It’s hard to see when on the wrist and only can been seen when looking closely at the dial. The person I purchased this watch from said it was serviced last year and I have had no issues.

Measurements:
37-38mm diameter without crown
18mm lug width
thickness approx. 12.7-13mm

I’m asking $1,800 USD for this piece. Please feel free to reach out with any questions or request more pictures.

Thanks
