This is the Sinn 103 St Sa UTC Diapal chronograph watch. It combines the classic look of the Sinn 103 series with Sinn's highly technical DIAPAL technology, which is so reliable that Sinn offers an unprecedented five year warranty on their DIAPAL watches. It has Sinn's "Dry Hold" technology to this model, consisting of a snowy white copper sulphate capsule and the use of Ar inert gas sealed within the case. The polished stainless steel case has a sapphire display back. Dial is a gorgeous anthracite with ebony black sub-dials, Arabic numerals and date display at 3. The design and layout of this watch make it extremely easy to read in virtually all light conditions. The sapphire crystal with luminous hands and hour markers, along with the skeleton hand for the UTC feature (or second time zone) glow brightly all night long. The second timezone sets independently of the main hour hand. The watch is water resistant to 20 ATM.

This particular watch is in excellent condition. There are no marks on the bezel, or insert, and only a few faint marks on the lugs from strap changes. It is keeping +3 seconds a day vs NIST. It is on a near new signed Sinn leather strap with Sinn buckle, and is marked waterproof. No box or papers. It lists for $3,570 from Watchbuys, and is hard to find. The screw down chrono pushers work as they should and zero exactly.
