Taking proper care of your watch and providing it with regular maintenance will help keep it working reliably, with precision and 

provide many years of functionality. 


Ensure that your watch is fitted properly on your wrist. This improves the efficiency of the winding system (for self-winding and manual watches) and avoids premature wear of the links of your metal bracelet. Avoid wearing several watches or items of jewellery on the same wrist, as doing so risks scratching the watch and metal bracelet links. 

We recommend having the bracelet cleaned once a year, right before summer to minimise wear and reduce the dirt build up.


Even if you have not worn your timepiece for a while, you should wind your mechanical watch (self-winding or manual-winding) at least once a month. For a manual-winding watch, turn the crown until it stops, without forcing it further. For a self-winding watch, we recommend at least 30 turns of the crown. This helps keep the movement components lubricate and reduce wear and tear.


The movement and the water resistance should be checked periodically. Water resistance seals exposed to the environment (temperature differences, acidity, amongst others) should be replaced every two to three years depending on wear and tear. This routine water-resistance service is the only way to protect the heart of your watch from dust and humidity. For self winding and manual watches we recommend 3 - 5 years, for Quartz watches we recommend every battery change, 18 months to 2 years.

For watches used for diving we recommend every battery change or every 12 months. 


Before swimming, check that the crown and push buttons are fully screwed down (if equipped). The push buttons should not be activated while submerged in water. After swimming in salt water, rinse the watch with fresh water always with the crown towards the ground.


Throughout everyday life, we are often exposed to magnetic fields that may cause timepieces to run slower, excessively fast, or even stop. If necessary, a simple demagnetization process can be performed by our professional watchmakers, before resetting the time. This is a free procedure we offer and takes less then two minutes. For this we use only the machines approved for service centre use, like the machine on the left.


Leather straps should not be submerged in water as water will wear them out faster. This does not apply to rubber or metal straps.

For water treated straps, the use around water should not be frequent.


Avoid correcting the date, month or lunar cycle in the afternoon or evening. Generally between 9 pm and 2 am. Similarly avoid manipulating the annual or perpetual calendar outside of the time ranges recommended in the watch manual.



A mechanical wristwatch is comprised of small gears, miniature screws & paper thin springs - as with any mechanical instruments that have constantly moving parts, a mechanical watch requires periodic maintenance.

As a watch ages the lubricants start to break down and the gears shift ever so slightly, and the accuracy of the watch will decline as well. The accuracy may be compensated by performing a couple of regulations over the course of a few years. We recommend the watch should be sent in every 3- 5 years - or sooner if you notice something amiss.

It is also recommended to have a water tightness test done, for watches that experience frequent water use every 12 month.
