I come begging for some superior wisdom from the fine folks of this forum.
I've across this watch and am seriously considering buying it. It's advertised as a 1958 ref # 2910 cal 284, 36mm without crown. To my amateur eyes, it looks to be in great shape and legit (although I can't find an exact match in the Omega Vintage archives at that calibre). Love the dial, the size, condition looks good.

What do you guys think? What would be a fair price for this, assuming it's relatively recently serviced? Asking price was around $850 - so I'm a bit nervous to wade in without getting the forum's feedback.
