I won this watch from Ebay a while ago, non working and newly surfaced from a house clearance.
It is a Rolco which was a brand of the Rolex watch co.
Courtesy of Mirius, it was found out that Balsom was the name of a Clockmaker/watchmaker who traded
in the Town of Reading...http://www.flickr.com/photos/carrie1...1797/lightbox/
The double hinged case is fully hallmarked for sterling silver being made in Switzerland and imported
to the UK with an X for Edinburgh import mark and Y date letter for 1929/30.
I just repaired and serviced this watch.
It required a new mainspring and a chipped jewel was replaced to the third wheel dial plate.
It now runs well and is a good timekeeper.
Whilst servicing the watch I noted the mark BTCo on the dial side.
The BTCo logo can be seen near the five o clock position, I wish I'd taken a better pic of just the logo but it's
to late now as the watch is assembled.
The O in Co is incorporated in the C on the top curve. I thought, at the time, that the watch movement would be an
easy I.D but it seems not as I can find no info on a BTCo and I don't know this movement!!
Can anyone Identify this movement? any info greatly appreciated, the movement is 25mm dia.
