Just sharing a review of my recently acquired pre-owned watches, which are not functioning.
Long story short, I got this pre-owned Seiko Perpetual calendar off a local e-commerce site Mxxxh.com It was listed as non-working and a discussion with the owner yielded no results.
As the price was too good to pass (RM70), I took the plunge and bought it on the off chance that it just needed a new battery.
It arrived and understandably, its crystal is scratched as described but none too bad. Opened it up and checked, the battery was flat. So off to get a new battery to test.
It was at this point after calling numerous electronics shop in JB that I found out that the required battery CR2412 is relatively rare. Finally managed to locate a supplier in KL which has it. Paid RM20 for the battery which is around 1/3 of the watch cost.
After digging around for the Service Manual for the procedure, I proceeded after the battery arrived. To sum it up the battery replacement was straightforward, but the resetting of the calendar settings was a nightmare. It was like short this tab & that tab to the (+) positive side of the battery. All the time turning the watch around to check the date indicator.
Finally done, much to my relief the watch was running and keeping correct time. A run of the calendar checking function showed everything was working well. Watch here:
