I repair them and collect them, I have dozens. Seikos are very good watches, cased as well as a Rolex. I just rebuilt a 1960s Bell Matic, a 27J automatic with alarm. Believe me, there are collectors that are just as selective about specific parts as the carbine bunch. Mechanical Timex watches are called pin lever non jeweled watches. They are not designed to be repaired, just worn until they die.The modern quartz Timex Indiglo are great useful watches for their price range.
