Silver Rolex Anyone ?

A friends watch which is an interesting piece a silver Rolec watch dont know anything about it wondered if anyone has seen one before.Havent got the watch now to take better photos but anyone who has an interest in watches will certainly know more than me thank you for any replies.

 

I don't know much about Rolex's but just have to say, that is about as much wear as I've ever seen on a watch. Sorry can't be of more help.

 

1920s, probably has Glasgow import marks for silver so not hard to get an exact date.

The movement is a routine 15 jewel lever typical of the period and pre-dating any of the Rolex innovations like the Oyster case.
The Rolex name will inflate the value although as a watch is is nothing special compared with similar watches from other makers.
