I had a poll between the Omega Railmaster and the Eberhard & Co. 8 Jours a few days earlier. I tried on both these watches (my dad has almost the same wrist size), and I also tried a GP Richeville. I was blown away by the simplicity and attention to detail on the GP, and I think my dad would love an understated "tank" style watch. I've spotted an NOS piece, and also plan to unload a few of my watches as I'd mentioned in the earlier thread.
Does anyone know about the GP cal. 2200-216? I couldn't find much info. about it except that it is a movement containing 21 jewels. Any help would be appreciated if there are owners of this watch/movement who can give me more information about it (pics would be even better!).
