This is a great example of an early Seiko digital. This A029-5020 is from 1978 and is a front pusher model which I really like. Unusual to see these in a blue dial. I found this one in working condition at a watch fair here in the UK. I paid under what the market value is as it needs a new crystal.
As you can see its had a good life! I managed to find a genuine Seiko crystal for this one at Cousins UK so set about fitting that and then also disassembling the module and giving it a good clean.
I could see a small amount of old battery leakage and a round in the ultrasonic cleaned that off nicely.
Now all I need to do is remove the old crystal and fit the new. As these have an inlay sandwiched between the glass and the case you have to be careful in how to remove the old. They nearly always break which is what happened to this one so you press slowly so when you hear it crack you can be nice and gentle.
I can now clean it all up a bit and then fit the new crystal and the watch is back in action!
Now the finished watch, what a different a crystal makes.
This watch also features on my Vintage Digital Watch Collection video from April 2024
