The Save the Ocean Asia Limited Edition version of the Seiko Prospex SRPH43K1 dive watch is Seiko's way of giving back to the deep sea.
Debuting late last year, the Seiko Prospex SRPH43K1 Save the Ocean Asia Limited Edition is the latest in a reasonably long line ofattempting to give back to the old big blue. Seiko has been on its own save the ocean drive for a couple of years now, and this latest model made waves on launch, no pun intended. In this region, Seiko’s latest on-the-ground efforts includes the coral protection education program of EEC Thailand , an environmental and social business organization in Thailand.
Seiko fans will know exactly what to expect from this hefty 43.8mm watch, but we will go over the key specifications momentarily. For the moment, we will pause to note that the reason we are talking up this model now is its silicone strap. Of the many types of material that could be used for dive watches, this one makes the most sense for everyday wear. The SRPH43K1 Asia Limited Edition is very much the sort of watch you could wear all the time.
Given that water-resistance is the first and best feature in terms of daily beaters, you cannot beat the 200m rating here. Silicone goes well with this extraordinary toughness, allowing the 12.8mm thick case to sit comfortably on the wrist — and more specifically directly in contact with skin.
On that note, the dial here is a stamped textured blue delight, which matches the strap . Again, this is a different beast to the other Save the Ocean variants, and the grid pattern on the dial is also a feature that many King Samurai variants share. Something a little different here is the unidirectional ceramic bezel, with orange markers that match the sweep second hand. On the dial, the hands and indices are all coated in Lumibrite, which is arguably superior to typical SuperLuminova.
