Our Attention to Detail
We design our watches to look stunning from every angle. It's like a piece of art on your wrist - show it off.
We are fascinated by the history and original usage of the watch. Throughout history, the wrist watch was an essential instrument with necessary functions that solved needs beyond just telling time. These iconic watch-wearing endeavors inspire each of our collection designs. Our designers want to tell those stories on every surface of our watches - even the back. So you can be proud to showcase your JM timepiece from all angles.
We design all of our watches to be resistant to water damage. So you can go anywhere, worry-free.
We understand that coming into contact with water is a daily occurrence. All Jack Mason watches are assembled and tested for water resistance of at least 10ATM (100 meters) to ensure safety from any day to day contact with water. An ATM is a unit of measurement used to indicate the water resistance of a watch. One atmosphere (ATM) equals 10 meters. We are committed to ensuring maximum protection against water damage so you can experience the feeling of worry-free watch wearing.
Even our buckles are designed to last. Tough enough to withstand your daily adventure.
When it comes to details, we don’t take shortcuts. We use detailed machine processes to cut the small tongue part of the buckle out of solid stainless steel. The result is a much stronger buckle attachment compared to a hammered/bent wire process. Using solid stainless steel for our buckle components means that you can venture on without concern of compromising your watch strap durability.
316L Stainless Steel
Our stainless steel lasts longer and resists corrosion. Strong enough to handle your everyday life.
All of our watches are made with grade 316 stainless steel which has a better resistance to chemicals and chlorides (like salt) than grade 304 stainless steel. Grade 304 is commonly used in fast fashion watch brands. 316L is a surgical grade stainless steel that is trusted for its durability and longevity. This level of quality is important to us because whether it involves water, sweat, heat or dirt, we don’t want you to stop doing what you do.
We protect our watches with the hardest crystal behind the diamond. Strength from the best offers protection for generations.
We design our watches to be protected with a sapphire crystal glass covering. In the watchmaking industry, it is common to use the cheaper counterpart to sapphire - mineral crystal. Mineral crystals are more prone to chips and scratches. Sapphire crystal, however, is the hardest, most scratch-resistant crystal behind the diamond. All Jack Mason watches come standard with sapphire crystals and an anti-reflective coating to reduce glare. So you can rest assured your JM timepiece is protected to last for generations to come.
