A watch that I paid £200 needs service amounting to £120 is a little stupid I think. Second Seiko minimum charge is £190 (could well be more) and the watch was about £250
I can get the case opened (have tools) but the cell that I replaced previously must have been a dud or old stock- it did not last long.
Will not be buying another Seiko but will consider a Citizen Ecodrive. These come with 5 year warranty.
Thank you all for responding.
