Band Material: 316L. This band uses the best 316L, which is a durable metal with light weight and high strength. It is corrosion resistant, non-magnetic and highly polished.
Watch Case: 316L. 316L is used as a case for daily seawater corrosion, and 316L steel is sufficient.
Case Back: Solid. We are using a solid bottom cover, which is more waterproof than transparent. A waterproof sealing ring is added to the through-bottom watch, which makes it difficult to seal.
Crystal: Mineral Glass. As an excellent watch, we applied it to isolate moisture and dust, protect the hands, dial and movement.
Hand: Silver-tone. As you can see in the pictures above, the hand design of the watch is silver-tone that is simple but luxury.
Second Markers: Minute Markers around the outer rim. The second mark on the outside of the clock is designed to indicate the time.
Dial Markers: Luminous Index. We can use a watch with a luminous stick, which allows you to see the time even in the absence of light and at night.
Luminiscence: Hands and Markers. The luminosity of the watch is hands and markers. It helps you know the according time when in dark.
Bezel Material: Stainless Steel. The bezel, made of stainless steel bezel, is more simple and endurable. It makes you improve your taste from the inside out.
Clasp: Fold Over Clasp. This watch case has a designed lock to make it easier and quicker for the user to open and fold the case over to keep it secure.
Water Resistance: 30 meters. A good waterproof of the watch has been applied, it is 30 meters. But please make sure you close the crown properly. Tips: The Automatic is just daily waterproof, need to purchase additional waterproof service which is up to 30 meters.
