I may have a spare soon but it depends how some works go. I will let you know if that happens. Having been down this rabbit hole the uncle seiko is also a nice option as a back up / for daily wear.
Sounds good Have as well some end links in my drawer if you look for something. Omega endlink 318 Omega endlink 549 Omega endlink 604 Omega endlink 618 Omega endlink 626 Omega endlink 633
Sorry the 653 did get used in the end so I just have 1x spare 120 (which does work for a 176.007) Good luck with your search. 653 do turn up but you need to be quick off the mark.
