Sinn is known for making dependable, well-built tool watches usually at an affordable price point. The Sinn 103 St Sa is no exception. With a chronograph, bi-directional countdown bezel, day-date indicator, and crown-guards, this is a watch built to be a functional and trustworthy daily wearer.
Powered by a reliable and easy to service movement, sapphire crystal, exhibition case back, screw down pushers, this is a watch with plenty to show off.
Also the classic and clean pilot look help a lot to make this one of Sinn’s best sellers and a constant presence in their line up for many years now.
This watch has some wear signs on case and bezel but it’s in overall good condition.
