The Seiko Prospex SPB315J1 is part of Seiko's extensive and legendary diving watch collection. 

This watch punches above its weight class with its impressive specifications. To start, this watch has a modest and very wearable 41mm in diameter, with a lug to lug distance of 46.9mm. 200m water resistance, a curved sapphire crystal and a high level of finishing are all part of the boxes that you can check on your 'diving watch wishlist'. What shouldn't be forgotten especially is the engine that powers this beast; the Seiko in-house Cal. 6R35 mechanical, automatic, movement, which features an impressive 70 hour power reserve. Definitely a drivetrain you can rely on.

The Seiko Prospex SPB315J1 features great lume and a very legible, utilitarian design that is ideal when diving and for every day practicality. There is little chance you won't know what time it is!

  2 year warranty

  We offer a 2 year warranty on all watches. This covers all mechanical malfunction arising from parts failure and/or assembly errors. Excluded are parts that by their nature may not last 2 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.
