    Quality product at a great price.

    I had the battery professionally installed & it works like a charm in my 30 year old Seiko kinetic watch keeping perfect time!!! The price point was was excellent & coupled with free shipping made it an easy décision to buy.

    Works well!

    I was a little apprehensive about opening this watch and removing screws that require tweezers to pick up but this really wasn’t a big issue other than keeping up with the screws during reassembly. This looks similar to a battery.

    Get a stuttering lorus kinetic running again

    When I bought my watch the label said "never change a battery" it is a lorus with a YT58B movement. Turns out that you may need to fit a capacitor and this one is the one that you need to get your old watch running again.

    Must be old stock.

    The capacitor will not reach full charge. I have been active, did the side to side recommended motion over a thousand times, 3 times and had it spin on a 40 rpm motor for 2 days and it still only charged for 20 seconds.
