Seizaiken1 x Seizaiken 377 SR66 AG4 SR626SW Silver Oxide 0% Mercury Watch Battery.

Excellent price, quick delivery. Saved me £8 by not having to go to the jeweller to get my watch battery changed.

Great product, value for money

Can’t believe it worked! Replaced by myself first time after getting fed up of paying nearly £20.00 in a high street repair shop.Amazing still can’t believe it’s much cheaper replacing at home.Delivery is impressive really quick delivery.Don’t know how long it lasts hoping for a year may be—

My miniature clock has managed 1year and 7 months on this battery. As far as I’m concerned, that’s pretty good by me . Probably best to order these critters one at a time when required , otherwise your spares may decharge in storage whilst waiting for their turn .So, yes, I’m ordering one again for my lil clock.💜😈

Delivered quickly and it is what was ordered. Price seems reasonable. The last one lasted 2 years, hopefully this will do the same.JC

I know it says 1 x but I assumed by the photo of a strip of 5 you would get 5 and didn't read the description properly (or at all :)). Just pointing out to others that might do the same as there are others that are better value.

Fast efficient delivery. Battery exact match for Skagen watch battery it was replacing. Worked perfectly and keeping good time. Too soon to say how long it will last but date good.

Good value, arrived quickly and long expiry life.
