Crystal: Sapphire Crystal. A good sapphire mirror is a high-quality optical material, often used in the construction of watches. The unique anti-reflective coating can provide scratch resistance without affecting its gloss. Tips: The Automatic is applied with mineral glass instead of sapphire.
Case Back: Solid. We use a sturdy bottom cover, which allows you to use and keep the watch for a long time.
Watch Case: 316L. 316L is used as a watch case that is corroded by daily seawater.
Band Material: 316L. The shell is made of 316L, which helps to form a corrosion protection film on the surface of the metal material.
Dial Markers: luminous dot. The watch has a luminous spot. When you are in the dark, you can know the time by looking at this spot.
Luminiscence: Hands and Markers. The luminiscence of the watch is hands and markers. It makes your watch look more high-end.
Second Markers: Minute Markers around the outer rim. The minute mark around the outer edge of the glass is a design element representing time, also called a clock hand, which has been used in many famous designs, such as watches and other objects.
Function: Date, Hour, Minute, Second. The watch has a time measurement function, that is, measuring time and seconds.
Bezel Material: Stainless Steel. A stainless steel bezel is a different way to look at watches. The design of the bezel brings a new level of quality and sophistication to the watch. This material allows for a more fused look and enhances the usability of the timepiece.
Clasp: Fold Over Clasp. Our watch uses a folding buckle strap, to make it easier and quicker for the user to open and fold the case over to keep it secure.
