The Marathon 46mm Jumbo Day/Date Automatic Rubber JDD WW194021SS, more commonly known as the JDD (Jumbo Day/Date) is an amazing and serious adventure watch, built to stand the test of nearly any challenge.

The 46mm diameter case with 55mm lug to lug distance has a substantial wrist presence, that will grace the right wrist extremely well. And where the watch especially will not let you down is under extreme circumstances, with the 300 meter water resistance and sapphire glass. And the star of the show is the amazing tritium lume, which has the benefit of not needing to be charged and it will function at all times.

Under the hood is a reliable, automatic, Swiss Made Sellita SW220 movement. 

Bringing an extra layer of comfort is Marathon's high-performance FKM rubber strap, that comes with 3 pieces (enabling 2 lengths), to ensure a very good fit on your wrist. This strap is made in Switzerland, as Marathon is fully committed to producing every part of their watches in a fully controlled environment, to their standards. 

The full model number of this watch is: WW194021SS-0130

  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.
