I tried to get a friend's Omega Time Computer repaired. The original battery size is no longer available - no problem, a pair of smaller NiMH batteries can be fitted into the battery recesses and held in place with a spacer. This done, the watch came to life - for a few days. Then it stopped working again. I thought maybe there had been excessive power drain causing the batteries to run down very quickly - but no, the batteries were fine.
I dropped the watch off at the local Omega service centre, from where it was sent to Switzerland - and returned a couple of months later with the message "Cannot be repaired - replacement part no longer available". The replacement part being the electronic control board.
This is Omega we're talking about. My understanding is that Omega sublicenced the movement from Pulsar, who made the very first LED watch (Omega being the second one to come to market in about 1972). Pulsar are still around. What gives?
Even scarier - an Omega Time Computer was sold with a two-year warranty at last year's Omegamania auction. How can they offer a warranty, when by their own admission they no longer keep spare parts???
By their very nature, electronic watches are disposable items. They will never last the distance, and there will never be a serious collector's market for them. How could anyone in their right mind invest in a "collectible" electronic watch? Even if it works today, it may stop working tomorrow, and if the chip is no longer made, that's the end of the watch.
