Faults: Some of the plating on the hands is worn off. There are a couple of scores on the case back (see pictures). There is a small amount of splitting at the spring bar / lug end of the strap (buckle side) and I have punched a couple of extra holes in the strap. The strap appears to be perfectly wearable as it is but the buyer may wish to choose another strap or bracelet for this. The strap size appears to be 19mm. I have said the case is in nice condition but it shows the normal tiny 'dings' you must expect with an older watch.
I can't vouch for this but I believe it has recently had a service.
This is a particularly nice watch but it is a vintage watch. I have taken care to describe it's positive and negative points as accurately as I can. It is not a blemish free watch therefore, if there is anything else specific you need to know about it in order to bid, please ask before bidding / buying. I will be happy to answer any question. Please do not expect a blemish free watch when bidding on a vintage and used one.
You may look forward to a swift dispatch and a well packaged item. .
