Watch battery replacement and pressure testing

We are experienced in the repair of almost every type and brand of watch here at WE Clark Watch Repairs. Perhaps the most common job we see on a day-to-day basis is replacing the watch battery.

It’s important to have your watch battery replaced by someone who knows what they’re doing for a variety of reasons. A professional watchmaker will have received proper training to look after your watch. In particular, if you have a nice watch from a prestigious brand, it really is worth letting someone with the appropriate training look it for you.

For example, trained watchmakers will, as part of the battery replacement service: check the entire watch, use good quality batteries, use the correct type of battery (you’d be amazed how often the incorrect battery is fitted), use correct methods fit the battery (eg. You won’t end up with fingerprints all over the insides of your watch) and use correct tooling (which will prevent damage to the case back and movement). As trained watchmakers we are fully capable of looking after your treasured watch.

Watch with Inspection Report

Alongside replacing the battery, we offer a pressure testing service for water resistant models. If you use your watch in water, it will need pressure testing to confirm it is sealed and suitable for use in water. A battery replacement and pressure testing is more involved than a standard battery replacement. In order for a watch to be sealed for use in water, all the seals must be in good condition and the case must be clean and not damaged in any way which could compromise its water resistance.

Once we are happy everything looks good to proceed with pressure testing, we put the watch in our top quality Sigma pressure testing machine. This machine is able to test the water resistance of watches up to a rating of 300m (30BAR). The test is conducted using air pressure, and the machine tests the deformation of the case. As this is a “dry” test, watches are able to be tested complete – i.e. with the movement inside the case.

We do also have the option to conduct a “wet” test. We most commonly use this machine to pinpoint where a seal is failing on a watch. A watch case without the movement is attached inside the machine and we then increase the air pressure. If there’s a failing seal, this means the inside of the case will be pressurised. The case is then immersed in water and the pressure is slowly released. A steady stream of bubbles will be visible at the location of the damaged seal.

Suffice to say, we offer a comprehensive watch battery replacement service. To take advantage of our expert watchmakers, quality tooling and state-of-the-art equipment, do get in touch. We are able to repair almost any watch and we offer a comprehensive watch repair service. We cater to clients all around the UK thanks to our fully insured freepost watch repairs service. As Business Partners of the British Horological Institute and a Feefo Platinum Trusted Service Award accredited business, you can be confident when dealing with us.
