Watch Battery Fitting & Resealing

Watch ~Water ~ Resistance ~ Testing ~ Sealing

We undertake resealing & testing on most modern watches down to the pressure
indicated on the dial or the case back, to a maximum of 10 Bar. Watches
requiring testing greater than 10 bar should go to the appointed agents
or specialist diving units. This could well involve new crowns/crown
seals, glass/glass seal, case back seal and appropriate silicon sealants.
The agent, subject to clauses usually offers a three to six months guarantee

Watch battery and pressure testing £32.00 inclusive.

Watch Battery fitting only £20.00 (no guarantee of water resistance).

Below is a guide to watch water-resistance values and their intended use.

*Water-Proof*

Old terminology which covered all types of Water-Resistance. Most timepieces bearing this claimant are well past their original efficiency and should, at best be treated as *Water Resistant*

*Water Resistant*

Timepieces marked *Water Resistant* by ISO 2281 have passed the following test only; 30 minutes under water at a depth of 1 m (3ft) followed by 90 seconds under a pressure corresponding to 20m (66ft) . *3 ATM* and *Water Resistant* are NOT suitable for swimming.

Usage

The crown must be in the normal or *Screw Down* position and must NOT be worked when wet. Dry with a soft cloth after immersion. Keep in mind that water-resistance is not a permanent condition. For example, the gaskets that are fitted in the crown, case back and glass will deteriorate with time and should be inspected and changed periodically. It is good practice to change the battery hatch or case back seals whenever the battery cell is changed.

*Misting* or *Fogging*

A drastic reduction of temperature turns moisture inside the watch to dew, which adheres to the inside surface of the case, the glass may become cloudy. The cloudy glass, will generally became clear in a few minuets, it is recommended to check the water resistant qualities of the timepiece. If the glass remains cloudy, urgent work is required.
