Seiko SRPB09K ‘Blue Lagoon’
Seiko persists in giving nd its watches dull reference numbers instead of names because it knows that its obsessive fans will christen each new watch themselves. This one has already acquired a nickname: the Blue Lagoon. At 44mm across, it’s bigger than a classic Rolex or Omega diver, and is limited to 6000 units worldwide. Seiko’s dive watches have been popular with working divers since the ’60s, and early examples are now very collectible.
