thanks. i hadn't looked up how to date it off serials yet, since i haven't dug through my tools for a case watch opener. this one has a screw on piece outside the caseback that holds it on.Steve O. wrote: ↑Sat Aug 31, 2024 12:21 pmFrom Fratello: "The crown on the SilverWave shows that Seiko is thinking about divers and the fact that many will be wearing gloves. Why does this matter? Well, the SilverWave has an internal, rotating timing bezel that is operated via turning the oversized crown." I may be wrong, but I believe that it rotates in the pushed in position. You may know this, but you can date the watch by the first two numbers and/or number and letter of the serial number. The first number is the year, the second number is the month. Starting with October, the first letter of the month was used. Since you know that your watch was produced from the early to mid '60s it will be easy to pinpoint. Hope this helps. Sorry to be so long winded. Great watch BTW.
doesn't feel like there's a way to push it in, and it's not turning when it's in it's normal set position. it's very possible the mechanism is toast. but i'll find out when i dig out that caseback tool.
working the polywatch on the crystal now. fingers crossed.
Thanks, Blaine.
