    Don't bother - go elsewhere for a product that will last
  

*by B***Z on Reviewed in the United Kingdom on 17 January 2015*

My previous battery lasted nearly two and half years, yet this one hardly lasted 5 months.  The trader only responded to me via amazon whereas their invoice indicated any query to use their direct email address.  All I would say is don't bother this method as I was totally ignored despite 3 emails!Eventually the trader responded and said "OK, I dont like the fact you feel we have not supplied the goods to standard. So I propose this. Buy an exact Seiko Seizaken elsewhere and if that lasts longer than ours, we will send you a cheque for the cost of the battery we supplied.(Or transfer the funds). This will show the facts, (the battery or the watch!). No limit on time, just forward the email with the result and we will action. We dont want unhappy customers, hope this will suit. Beaky"Can I suggest it might be easier to use another trader in the first place as this was the case with my previous battery.Could think of an obvious solution but.......................................

    Watch Battery
  

*by P***N on Reviewed in the United Kingdom on 23 April 2012*

I prefer to replace my own watch batteries as we do not live near any shops so the cost of driving, parking and actually finding the correct battery is prohibitive. This seller gives a fast reliable service and saves me a considerable amount of money. The battery is a good quality one that has not caused us any problem.

    Exactly as needed
  

*by A***S on Reviewed in the United Kingdom on 12 March 2013*

Very prompt delivery, well packaged and it worked! Top quality battery. What more can I say - apart from, buy the very cheap but useful watch repair kit on Amazon if you want to get the back off a well made Seiko watch.
