Seiko Men's Superior Automatic Diver's 100M Stainless Steel Watch SRP447K1 - Black
As did its predecessors, this watch looks great, keeps accurate time (for a mechanical watch), and feels solid and rugged. I've not had it diving, yet, but I'm sure my 100 foot dives will not tax its 200M rating. After a week of ownership, it is gaining 5.5 seconds per day. Since it is hackable, it will be easy to synchronize, useful for military-types who have time-on-target or other precision timing needs.Feature- Stainless Steel Case- Stainless Steel Bracelet- Automatic Movement With Manual Winding Mechanism- Caliber 4R35, 23 Jewels, Hardlex Crystal- Black Dial, Bezel, Date Window- See Through Case Back- Three-fold Clasp- 100M Water ResistanceSpecificationProduct Model:Seiko Men's Superior Automatic Diver's 100M Stainless Steel Watch SRP447K1 - BlackGeneralGender:MenDisplay type:AnalogWater resistance:100 metersSizeCase diameter:41 mm
