Watch Repairs, Servicing & Batteries

Battery Replacement & Pressure Testing

Our same day battery replacement service is available in-store. Battery replacement is carried out by experienced staff who are used to working with high calibre watches. Our high quality leak proof batteries are guaranteed for 12 months however this service carries no guarantee on the water resistancy.

For the more discerning client we offer a “Pressure testing” battery replacement service. This service includes replacement of the battery, replacement of the seals, checking of the movement and timekeeping functions. Ultrasonic cleaning of the case and bracelet. Checking of the bracelet clasp and fittings. Testing of the water resistancy to the original specifications of the watch.

This service offers a 6 month guarantee on the battery and the water resistancy. It is carried out by Robert Openshaw's fully qualified watchmaker in our specialist workshop and typically takes 7-10 days.

Current norms state that a watch can only be called "Water-resistant" if it withstands perspiration, drops of water, rain, or immersion in one meter of water for 30 minutes. Superior levels of water-resistance are generally indicated on the dial or the case in the form of bars of pressure or a depth in meters. Diving watches are subjected to even more stringent tests. They must be capable of being used for at least one hour a day at a depth of 100 meters. It is important to remember that the water-resistance of a watch is tested at a particular point in time and is not guaranteed for life. Any work on the case, or strong changes of temperature (e.g. taking a cold shower after lying in the sun), as well as the ageing of materials can lead to moisture penetrating the most water-resistant watch.
