Sinn Spezialuhren 144 Ti DIAPAL

The Sinn 144 Ti DIAPAL, reference 144.078, is a titanium chronograph with a 41 mm case and a second time zone. The bead-blasted case has a see-through back, measures 14.5 mm thick and is water resistant to 200 metres. Calibre Valjoux 7750 winds automatically, while DIAPAL supplies a lubricant-free escapement. A sapphire crystal covers the grey dial with its date and small seconds displays. Ar-Dehumidifying Technology limits fogging. The dial includes a tachymeter scale around the indications.
