Watch batteries

Watch batteries come in many different forms in terms of size, power, type, brand and quality. Most quartz watches use 1.5V Silver Oxide batteries of which there are in excess of 40 different sizes in common use. LCD (liquid crystal display) or digital watches tend to use 3 volt lithium batteries. Some watches including one from Omega use an unusual 2 volt lithium battery.

Regarding quality, the watch repair marketplace is unregulated and thus many inferior batteries are sold & fitted by both jewellers and ‘repairers’. In recent times there has been a flood of alkaline watch batteries entering the market. Alkaline batteries are completely useless for watches as their power reserve and performance dips from day 1. For example if a torch is left on for a number of hours, it will of course be considerably dimmer and if left the beam will just fade away. These batteries are unfortunately commonly fitted in watches too. After these cells have spent their energy, they are prone to leakage and will destroy the movement in a watch.

Many battery brands are used in the marketplace. Common ones are Maxell, Rayovac, Sony and Varta. The WATCH Lab uses Renata wherever possible. These tend to be the most expensive but are in our view the best. Renata is a Swiss made battery manufacturing company owned by Swatch Group (Omega, Longines, Hamilton, Breguet etc).  In The WATCH Lab’s experience, Renata batteries are the most reliable and last the longest too. They are also the battery of choice fitted by premier Swiss watch houses including Tag HEUER, Breitling, Chopard and even Rolex for their quartz collections.
