The old Seiko arrived from Japan! It is in quite good condition - the dial looks great, the case and crystal need a polish. The strap is falling apart but I don't know if it was original

The movement looks great. The watch is not running, but importantly the balance is in good condition. It appears to be overbanked, but the pivots are not broken. This is why the watch was like $45. In good condition they for for around $250 on ebay.

Can't wait to dive into it tomorrow

Edit: Yup the mainspring is broken, just need to replace it. These are not meant to be serviced, so it's tricky to get into them. I saw somewhere that you can use compressed air to pop them open, and that sounds like the best idea. Razor blades can work, but there is a 0% chance to not leave a mark. I used one on 68's because it looks like it had been opened up that way on several occasions over the years

Based on the condition of all the screws, etc, I don't think this watch had ever been worked on before. It definitely got worn, but I'm pretty sure this is its first service ever!
