We use 316L surgical grade stainless steel.

We use Swiss quartz movement by Ronda. Ronda quartz movements have a good reputation for being extremely reliable. Very long battery life, up to 10 years.

Our batteries are expected to last up to 10 years, but not limited to: external

temperature, humidity, air pressure etc.

Please set the time to 12:00 sharp and check that the crown is pushed in, completely, against the watch case. Wait 15 minutes to see if the minute hand has moved. If this does not resolve the issue, kindly contact us and we will be happy to assist you: Contact us

We use sapphire crystal glass. The glass is scratch resistant. Sapphire glass is second hardest material on earth.

The water resistance of a Greisz timepiece is at least 5ATM of water resistance. Withstands pressures equivalent to a depth of 50 meters. Suitable for everyday use, showering and swimming. Not suitable for diving. When using the watch in and around water, do not pull out the crown to change the time. Certain chemicals in water can damage the watch seal as well as perfumes, aerosol sprays and other cosmetics. The gaskets need to be replaced by time to maintain water resistance. Rinse off your watch with fresh water to remove any salt or chemicals. 

Clean your watch by using a damp cloth. Exposing your watch to chemicals like soap, detergents, cosmetics and perfumes can damage your watch case or strap. Exposure to direct sunlight can cause fading on the watch or strap. Service your watch regulary. Ideally, a mechanical watch should be serviced every two years, while a quartz watch can be serviced every three years. Replace a dead battery as soon as possible to avoid the risk of leakage that can cause a serious damage to the watch. Never open your watch by yourself, it can impact the water resistance of the watch.

We use Genuine Italian Leather for all of our leather straps.

Yes, all of our straps are designed to be swapped in and out in a few seconds and without tools. Simply insert one end of the spring bar into the lug and then slide the quick release lever with your finger.

Avoid creasing the strap. Wipe the strap gently using a soft rag with warm water. Next apply a premium leather conditioner by applying a small amount to your fingers and gently massaging it into your strap. Always test the conditioner on the back of the band first and be careful not to get too much in the stitching as some conditioners can dry white and can be difficult to remove.

Yes, gently scrub the mesh strap with a mix of water and just a little bit of detergent using a toothbrush or similar.
