I wish to state that i sent my seiko 6105 8110 to Peter of eastcostwatchmaker for a full service and relume using original vintage factory seiko lume and the workmanship was superb. I am totally happy with Peter’s work. Not only is the watch running within the new seiko watch parameters but he replaced parts using original seiko parts ( apart from crystal which is a high grade oem) . He alos replaced all gaskets and he pressure tested the watch and rebuilt the crown so that this watch can be used for DIVING. I have taken it DIVING to depth of 40m underwater and i am totally amazed that it functions perfectly despite warnings dont swim /dive with vintage watches. I have swim with it too. THis watch was pressured tested to 100m by Peter and it performed flawless after replacing the old crown and tube with original seiko vintage parts. THIS IS A 1973 WATCH! Peter was brillant in comunications and sent me video clips of pressure test and timing readings. Originally i wanted to send my watch to Mr Spencer Klein of Spencer Klien vintage a legend in seiko circles but the waiting list is over a year and i am so lucky to have found peter because his work is fantastic. Furthermore the service and relume was done in under a month and a half . I certainly will be sending him more vintage seikos for service, repair or overhaul. My watch is like new now thanks to Peter . I have no hesitation recommending Peter as an honest and very capable watchmaker .
