All you need to know about watch batteries

The only battery made by a watch
manufacturer specifically for watches

In response to questions as to why our batteries are more expensive than in other Jersey jewellery shops, the answer is simply that we are not, we are by far the most cost effective.

Prices in Jersey for watch batteries vary from between £1.50 (us for Alkaline batteries) and £50 (Ernest Jones) but it is important that you understand what you are paying for.

The next cheapest is TJ Hutchings who will supply alkaline batteries for £2.00.

We are the sole stockists of Seiko watch batteries and with a fitted charge of just £4.50 or £2.00 for the battery we invite you to compare our prices on any internet site.

We also will supply inferior batteries at prices which are lower than other jewellers in Jersey, the standard silver oxide battery we will fit for £3.00 or if you really want an alkaline battery then these are fitted for just £1.50 but they will damage your watch.

The Seiko Battery

Seiko's Micro-Energy Division has commercialized a highly reliable silver oxide battery in response to quartz watches. Since then the company has expanded its micro-battery business. With rapid progress in LSI technologies, highly advanced micro-batteries are now being strongly demanded for sophisticated electronic instruments and equipment. The company continues its best efforts to develop high performance micro-batteries which meet any users' needs and requirements. 

The unique feature of these batteries is that they are guaranteed not to leak due to the double walled design, similar to that of an ocean going ship so even if one wall fails, there is another to protect the workings of your watch.

Silver Oxide Battery

Silver oxide batteries are noted for their high energy density and ability to put out high current for their size. But they are extremely expensive because of the cost of the silver. To produce them in large sizes is not cost effective, except for some military applications. But for miniature devices where space is severely limited, like watches, hearing aids, calculators and some photographic equipment, they are ideal and will last much longer than their 'cheaper' counterparts. A silver oxide battery should never be placed in a charger.

Alkaline Battery

Alkaline batteries are the most common choice where economy is important. They have a tendency to leak, making them less attractive than silver oxide because they can cause corrosion and damage equipment. Alkaline batteries may come in rechargeable versions.

Additional Services

Once your watch battery has been changed then the watch is no longer water resistant, the watch will need to be tested and if necessary the seals will need to be replaced in order to retain its water resistance. This service is not included in the prices quoted above and you will need to request this service if it is required.
