[Alcan]

1960's cocktail watch (most earlier ones were 9k), faceted crystal, probably with a caliber 1400 or 1401, the smallest movements Rolex has made.

Not much market for them, usually in the $1,200 - $1,500 range, but still a nice looking watch.

Check for a hallmark on the inside case back. If so, any jeweller can nail down the year the case was made.
