The Seiko Prospex Tuna 'Save The Ocean' SRPH77K1 goes all the way back to 1975 when the first 'Tuna' was released. A design that immediately catches the eye, due to the protective shroud that protects the body of the watch case and somewhat resembles a tuna can (hence the nickname!).

This model is outspoken, but also very comfortable. Traditional watch design is of course very rectangular, but when you take a more rounded shape it also means it will fit nicely to the center of your wrist. The SRPH77K1 is a mere is 43.2mm in diameter, but the lug to lug distance is a mere 44mm. That means while it is big in diameter, the vertical distance is closer to what a 38-40mm watch would feature.

The watch is also part of the 'Save The Ocean' line, of which Seiko makes several designs, in collaboration Fabien Cousteau, the grandson of the legendary ocean explorer Jacques Cousteau. A portion of the sales from these timepieces are donated to ocean conservation efforts.

However before we get too caught up with what this watch is about, we shouldn't forget that it is also a very good... watch! It features an in-house made mechanical (automatic) Seiko Cal. 4R35 movement - a good, reliable workhorse movement that will keep on ticking! The stunning dial is protected by the Seiko Hardlex mineral glass and you can use this beauty up to 200m.

Special, comfortable, interesting, strange, practical and carrying a rich pedigree. Definitely not your average watch, but it's better to be a tuna than average!

  3 year warranty

  Seiko watches come with a 3 year warranty. This covers all mechanical malfunction arising from parts failure and/or assembly errors. Excluded are parts that by their nature may not last 3 years, like batteries and leather straps, damage/problems caused by improper use and wear and tear. We stand behind the brands that we sell and the quality that they offer.
  Some of our brands also offer an international warranty, which will also apply.

  Service and parts

  In the unfortunate event of a problem with your watch, you simply need to send it to us (or take it to another dealer if the brand offers an international warranty). We have access to the official service centers, where only original parts are used and the watchmakers are qualified and experienced with your type of watch. Not every watch movement is the same, so it's best if it's handled by people who know what they are doing.
  After your 2 years warranty has expired we are able to offer service in most cases.
