Seiko Prospex "Baby Tuna" Automatic Diver's 200M SRP641 SRP641K1 SRP641K Men's Watch

Seiko Prospex "Baby Tuna" Automatic Diver's 200M SRP641 SRP641K1 SRP641K Men's Watch This new Baby Tuna is a part of Seiko's international Prospex releases. The shroud is different here; it is hardened composite material and the movement, a self-winding Seiko 4R36. It has both hack and manual winding features and the hardened mineral on top is a Hardlex crystal. It is still the best for shatter resistance while the Lumibrite lume takes a minute in the sunlight to charge and glow brightly for the next 15 minutes. http://www.creationwatches.com/products/seiko-prospex-299/seiko-prospex-baby-tuna-automatic-divers-200m-srp641-srp641k1-srp641k-mens-watch-6375.html
