Seiko Prospex Speedtimer x Datsun Limited Edition

Produced as a limited edition, the Seiko Prospex Speedtimer x Datsun Limited Edition carries LIMITED EDITION and an engraved serial number on its screw case back. The 42 mm stainless steel case has a hard coating and is worn on a cow leather strap.

Inside, the 34-jewel 8R48 calibre powers a mechanical chronograph measuring up to 30 minutes and 12 hours, and a tachymeter lets you calculate speed over a measured distance. It winds automatically or by hand, holds around 45 hours of power and runs to +25 to -15 seconds per day. LumiBrite on the hands and indexes, a dual-curved sapphire crystal with anti-reflective inner coating, 4,800 A/m magnetic resistance and 10 bar water resistance complete it. It fastens with a three-fold clasp and comes with a 3-year international warranty.
