Watch battery

  • Both silver oxide and lithium.

  • We only offer watch batteries of recent manufacture with expiration date far and bought in Europe. 

The introduction of button cells in the world of watchmaking is intimately linked to the introduction of the quartz watch. Although the first quartz watch has been dated back to 1920, it was not until 1967 when Seiko launched, with its popular slogan “Someday all the watches will be like this", the first prototypes of wristwatch. It would be in the Christmas of 1969 when the first commercial model was put on sale, the Seiko Quartz Astron 35SQ. We can put the starting point of the history of batteries in watchmaking world. Most analog and many digital clocks use silver oxide batteries which offer a voltage of 1.55V. Some watches, mainly digital, use lithium batteries, which offer a voltage of 3V. These types of batteries are also used in the electronics industry.For example, on motherboards of PCs, remote controls of doors, cars, etc.

There is a cheaper option, alkaline carbon batteries. But honestly, except for some sporadic applications and some very specific references, they are not worth it.

If you need to replace the battery of your watch, our recommendation is to go to a watch shop. It is becoming more frequent to see that the change of batteries is offered in other types of establishments.For example, we see it in a multitude of bazaars. We're going to tell you some reasons why you should not change the battery of your watch in one of those establishments:


  • Battery quality- Usually these types of establishments use alkaline batteries of coal. No silver oxide batteries. You will be telling yourself “what difference does it make? The fact is that my watch is working”. That is a mistake. It makes a difference. If you are very lucky, your battery will last much less than one of silver oxide. But the most regular is when the battery is worn it will sully and damage the machine of your watch. t is as if you put a bad oil on your car and end up with the engine seized.Is it really worth it for the price difference?
  • "Opening a watch is relatively simple. Anyone can do it” … I do not know how many times I've heard this phrase. What if. There may be some truth. It all depends on the brand of the watch and the type of lid of the box. A watchmaker will know and will have tools to open almost any type of box. The watchmaker's tool isn’t cheap. In an establishment outside the clock shop will end up opening the watch with an inappropriate tool and scratch the watch case. However, this is not the biggest problem.
  • If opening a watch case may seem easy, closing it is something else.Again, the professional has the appropriate tools to close your watch again. Even in good watchmaking they can guarantee you that it is still submersible if you want it. In the corner store that in addition to selling a can of your favorite soda offers you change the battery of the watch, will not be able to close without damaging the glass.Any professional in watchmaking is tired of seeing a customer with the watch open because where he took it to change the stack did not know how to close it. Or worse, it comes with broken glass.
  • There are plenty of models of silver oxide batteries, but only the most popular have their alkaline equivalent. All have the same voltage, 1.55V but have different dimensions (diameter and height). In the end, this type of establishment put the most similar and "fit in" as they can. With any movement, a little rough will lose contact and your watch will stop.
  • Expiration. Yes, even the clock batteries reach programmed obsolescence. J. In a watchmaking, the professional will worry about having the necessary stock to attend to its clientele, but always with the care of having an adequate rotation. If the battery is charged with less than the proper charge and the watch will stop in a few months. Even the battery could burst and damage the watch machine.
  • If you are also one of those who care about the environment, you will like to know that no watchmaker ever throws a pile in the trash. Within the watch industry, the concept of recycling of watch batteries is already old. In other types of establishments, the battery removed from your watch will go directly to the bin. Can you imagine what can contaminate a clock battery thrown away?

Sure, there is something obvious, the price is not the same. A watchmaker will charge between € 3.5 and € 5 for changing a normal battery. We're talking about a normal watch with a normal battery. In the shop where you buy the bread you will be charged between € 1 and € 2. But the chances of running out of time are sky-high.

I heard an excellent professional tell a customer that he did not charge € 3.5 for a battery, charged € 3.5 to know how to put the battery, without mistreating his watch and with the guarantee that his watch would not suffer any damage, nor would it stop in 3 months because it was left without battery again.

As for the duration of the battery, depends on many factors, mainly the machine that carries your watch and the functions of it. As a rule, a silver oxide battery lasts between 1 and 3 years. One lithium, between 3 and 10 years.

At Diloy we only work with batteries from famous brands. We are now comfortable working with Sony. We only use batteries for the European market so its expiration date is wide enough for the professional to sell it to the end customer.

Finally, as we firmly believe that it is the professional watchmaker who should replace the battery of your watch, we only sell boxes of 10 batteries. Normal amount for a professional but illogical for a final customer.
