The Yema Skin Diver Black CMM.20 12.25.20.66.SN.M3 takes the concept of a 60s skin diving watch to the next level. Simply every element of the watches of yesteryear have been improved. 

To begin the watch is staying true to elegant sizing, as the case measures 39.5mm in diameter (excluding crown) and is a mere 11.5mm thick (excluding crystal). The watch features a new bezel system, to help prevent accidental rotation. During normal operations the bezel is locked, but to rotate it, you first need to press it down and you can then move it bidirectionally. The insert of the bezel is scratch resistant sapphire glass.

Innovation doesn't end there, as the watch also features an adaptive glide micro-adjustment system in the clasp, to ensure it can be fitted to your wrist comfortably in incremental adjustments of 1mm. No tools needed and comfort guaranteed.

Under the hood is the Yema manufacture Caliber CMM.20. This amazing in-house movement is produced in Switzerland and France and has an impressive 70 hour power reserve and operates with an accuracy of +7 and -3 seconds per day. But perhaps the most amazing thing is the bi-directional tungsten micro-rotor, which allows the movement to be incredibly thin at just 3.7mm in thickness. And it's not just good in performance, this beautiful masterpiece is also visible through the caseback window.

Yema has brought all the comforts, materials and qualities of today to a watch that embraces the design pedigree of the past. A true modern masterpiece!

  WSarranty

  All Yema watches come with a 2 year warranty. The watches featuring a manufacture movement even come with a 5 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 the entire warranty period, such as 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.
