Seiko Alpinist Compass Bearing Function 39.5mm Mens Strap Watch

Ref. SPB121J1

A dark green sunburst dial sits at the heart of this 39.5mm stainless steel case, its surface shifting tone as the viewing angle changes. Cathedral hands and applied hour markers carry LumiBrite luminescence, while the date appears at 3 o'clock beneath a sapphire crystal fitted with a cyclops magnifier and inner anti-reflective coating. The case combines brushed and polished finishing, with a see-through caseback revealing the 6R35 movement. Two crowns define the design: one at 3 o'clock for winding and setting, one at 4 o'clock operating the rotating inner compass bezel. The calibre offers 70 hours of power reserve, a hacking seconds function, and manual winding. A brown calfskin strap with alligator print closes with a three-fold deployant clasp.
