Seiko Prospex Baby Tuna "Save The Ocean Antarctica” Penguin Dial Dive Watch #SRPH77

The Seiko Prospex SRPH77 is a Save the Ocean model. Seiko donates a portion of the sales to the Fabian Cousteau centre. The watch has a crisp textured green dial featuring swimming penguins embossed on the left side. The movement is a reliable 24-jewel Seiko caliber 4R35 automatic that can be hand wound and hacked. The powerful Seiko LumiBrite luminescent material provides brilliant glowing properties for reading time in the dark. A nice touch on this new model is that the case back indicates that it is a special edition.

Lug width is 20mm. Case size is 43mm in diameter x 13mm thick and 44mm tip to tip. It has a Hardlex mineral crystal and a (120-click) dive bezel. The supple rubber strap is a matching greenish-blue. It is a perfect match for the theme of this watch. Water resistant to 200 meters with a screw-down crown and caseback. Weight is 103 grams. 20mm lug width.

Note: the 43mm case diameter tends to wear smaller due to the short lugs on this model. It is about 5mm shorter than the Seiko Monster version of this watch.
