Basic tips for your watch

Watch winding
Wind your mechanical watch on a regular basis. Even if you do not regularly wear the watch, wind it at least once a month. This ensures that the lubricants remain elastic in the timepiece.

When winding your mechanical watch take your watch off your wrist to damage the mechanism as little as possible. Always wind your watch clockwise with the hands.

In general, it is better not to adjust your time between 9 pm and 3 am, as this could damage the date mechanism.

Make sure your watch is not in direct contact with magnetic fields (such as speakers, TV, microwave, magnetic closure, iPad case, etc.).

Preventing damages
Even though your watch is "shockproof" always try to protect against hard knocks and shocks. Tennis and golf are risky sports for your watch.

If the glass of your watch breaks or cracks, have it replaced immediately. Even through a small crack in the glass dust and moisture penetrates and damages the interior.

If the battery in your watch is empty, have it replaced immediately. Exhausted batteries may leak and this could damage the interior.



  • Make sure your watch is not exposed to extreme temperature changes
  • Do not put your watch directly from your wrist onto a cold surface
  • Never wear your watch in the sauna, as the seal on your watch can deform by the heat. If there is water or condensation inside your watch, have it checked, even if the watch is still running.




A common misconception is the water resistance of the watch. Make sure you are well informed about this and check the warranty. Moisture causes corrosion, which can damage the watch severely.

Watches that are waterproof, have an indication of the number of meters to which the waterproof is guaranteed. General rules for water resistance:

  • 3 atm.: water splashes, rain
  • 5 atm.: swimming ( not diving), showering
  • 10 atm.: water sport, swimming, snorkelling, diving
  • 20 atm.: suitable for all types of diving

The water resistance of a watch is guaranteed by various rubber gaskets in the watchcase: around the crown, the back cover, the glass and possibly the pushers (buttons). These gaskets are permanently under pressure and may be affected by moisture, detergents, UV radiation, dirt as well as wear and tear on the watch case. As a result, the rubber dries over time. This decreases the water resistance.

It is essential that the wearer checks his or her watch annually for water resistance. When replacing a battery, we replace all gaskets and we test if the watch is waterproof.

Accuracy of your watch

A mechanical often shows small time differences. The exact time can only be ensured with an electronic watch (radio controlled).

Depending on the quality of the watch, the time on mechanical watches may vary from -5 to +10 seconds per day. The Swiss Official Chronometer Control tolerates an average deviation of -4 to +6 seconds per 24 hours.

The high demand for a minimum time-loss of several seconds per day can only be made on the modern brand watches like Patek Philippe, IWC, Omega, Vacheron Constantin, Rolex, etc. Schaap en Citroen regulates modern mechanical watches to be about +10 seconds per day. Wearing the watch has a slowing effect at all times, so the watch is always adjusted to +10 seconds.

Vintage and antique watches may vary more because of tear and wear. Age also plays a role. 

As oil ages, a watch will also run more slowly. After the oil is about 4 years old it requires major maintenance. Thus, internal damaging is reduced to a minimum.

To provide a perfect adjustment of the watch, the watchmaker will balance the spring, the heart of any mechanical clock, again. ensure comprehensive testing and long-term observations that the timepiece is functioning exactly.

Your Watch Strap

Your strap needs servicing. Depending on the material, we recommend the following maintenance tips.

Leather Strap
Leather is a wonderful natural product and as a watch strap is very suitable. Quality straps are sometimes very expensive, which may be due to the special leather, design and / or craftsmanship.

For optimal maintenance, do not wear at night so the leather gets rest. If the strap gets wet by water or sweat, let the strap dry before the watch is worn again. In very hot weather, it is best to loosen the closure by adjusting a hole or take off the watch a few hours. The leather becomes less humid and the strap doesn't smell. For exercising or performing or rough and wet work, it is best to take off the watch.

Through the use of a butterfly clasp the strap will live longer. With a buckle clasp the strap breaks first at the place where it closes.

Metal Straps
Metal straps may cause a black wrist. That's because there are contaminants on it (sand, fine dust, sebum etc.). Make sure you have strap cleaned ultrasonically on a regular basis. Heavy watch straps are often lubricated at the hinge pins. This slows down the wear and tear. You can maintain your metal strap, if necessary, along with the periodic maintenance performed on your watch.



Your watch deserves the best possible care. Like any other precision machinery, a high-quality watch should also be checked regularly. To ensure long life and long-term reliable performance, maintenance and repairs must be carried out according to strict brand specifications. Therefore only original parts will be used.

This chapter takes you through the steps that are performed at periodic maintenance.

1. The identification of your watch
Thanks to a unique numbering and identification, your watch always undergoes the proper maintenance and repair procedures.

2. Technical diagnosis
First, a highly skilled watchmaker makes a comprehensive analysis of your watch, the cabinet, the strap and - especially - the movement controls meticulously. He can determine what maintenance your watch requires.

3. Taking the watch apart
The next step consists of the opening of the cabinet and the removal of the watch strap. The timepiece is taken out of the cabinet, and all the parts are taken apart. More complex movements consist of hundreds of individual components.

4. Cleaning
All parts are then cleaned in the appropriate liquids. Only when all parts are cleaned, each part will be separately checked in detail.

5. Replacing parts
The watchmaker replaces any parts that show signs of wear or that could interfere with the precise operation of the timepiece. Here he follows the manufacturer's instructions closely.

6. Lubricants
There's a specific lubricant for each individual component. Special oils of different viscosity are applied exactly where necessary.

7. Checking the timepiece
Through an electronic machine, the watchmaker can detect deviations and errors in the course of the movement.

8. Adjustment
To provide a perfect adjustment of the timepiece, the watchmaker, adjusts the balance spring, which is the heart of any mechanical clock. Extensive testing and long-term observations guarantee that the timepiece is functioning correctly.

9. Restoring the watchcase
After the watch is cleaned in an ultrasonic bath, damaged parts will be replaced. The case is prepared and polished by hand, so the watch gets its sophisticated appearance back.

10. Assembly
Finally, the watch is carefully put together and all seals are replaced.

11. Waterproof test
The watch is checked for tightness through quality testing equipment.

12. Quality Control
Each step in and after the maintenance process is extensively checked in the watchmaker's workshop. Finally, the watchmaker monitors all key parameters of each component again.

13. You will receive your watch.


After an extensive service and repair Schaap en Citroen will provide a 2 year warranty on the performed work. This warranty does not cover tear and wear or damage caused by improper handling of the watch. The maintenance warranty is void if the watch is opened by an unauthorized third party or if non-original parts are used.
