The Formex REEF 39.5mm Automatic Chronometer 300m Green Rubber is a phenomenal, stylish, well-made and extremely comfortable high-end Swiss Made diving watch. The watch is extremely comfortable and elegant with its 39.5mm case and mere 11.0mm thickness. To complement this the watch features a rubber strap with a deployant clasp made of carbon fiber with Micro-extension function. This also shows the level of dedication towards detail that is present throughout the entire watch. The watch is also very well suited for diving and water sports, due to the 300m water resistance and unidirectional ceramic bezel that you can remove and exchange without any special tools (a fingernail is sufficient!).

It doesn't end there, as the watch features a Swiss Made Sellita SW300-1 mechanical (automatic) movement that is COSC certified, ensuring that it runs +6/-4 seconds per day and meets all the strict testing criteria of the Contrôle Officiel Suisse des Chronomètres.

Of course the watch features all the things you'd expect from a high-end watch, such as BGW9 Super-LumiNova lume, sapphire glass with an AR coating and 300 meter water resistance. 

Formex offers an extremely high level of quality, finishing and specifications at a very competitive price. The REEF is the most amazing diving watch in this price range, by a long shot!

Please note that while the 39.5mm and 42mm versions share the same bracelets and straps, the bezels are not interchangeable between these 2 lines.

  3 year warranty

  We offer a 3 year warranty on Formex watches. 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.
