About my Delma
A reference number is a unique number to identify each Delma watch model type, like the Klondike Moonphase in stainless steel (Ref. 41701.680.6), or the Oceanmaster Chronograph with rubber strap (Ref. 41501.678.6). You can find the reference number on the case-back of your watch or in the Delma warranty booklet handed to you with the watch at purchase.
Service & Maintenance
In order to wear a watch while swimming, it needs to be water resistant up to 5 ATM (50 m / 165 ft) at least. For water sports like diving, snorkeling and surfing a water resistance up to 10 ATM (100 m / 330 ft) is required. Delma strongly recommends that leather straps are not to be used in water, rubber straps and metal bracelets on the other hand are fine.
Delma watches with a water resistance of 5 ATM (50 meters /165 ft) or more that have recently been checked, can be cleaned with warm fresh water and a drop of a soft liquid soap, then dried with microfiber cloth. For vintage Delma watches or if you are not sure about the water resistance of the watch being intact, you can moisten a microfiber towel and gently wipe the watch.
Please bear in mind that after swimming and diving in salt water you should always rinse off your watch with fresh water.
The bronze material selected by DELMA for its divers’ watches is a high-quality alloy that is widely used in the marine world and is known for its durability and corrosion resistance. It is normal for bronze to form an oxide layer over time, called patina, a protective skin that covers the metal. Each patina is different, giving each bronze watch a truly unique look. The patina can be removed but it is normal for subtle changes in the color to remain.
Mechanical watches should be serviced every 3 to 5 years to ensure the longevity of the movement. To send in your mechanical Delma watch for a service please contact your local Delma service center or us directly. Please do not send in your watch for service without prior contact.
Quartz watches will require a battery replacement, other than that the movement does not demand any servicing. You can do this at your local Delma service center.
We further recommend you have your Delma watch checked for water resistance once per year. This can be done at your local Delma service center.
