Change in the movement During the period 1949-52 the
F3 movement was made shallower. It was reduced by 10mm and became
known as the F7 movement. On the time timepiece side, the same
depth of movement was also reduced to incorporate a new plastic
kitchen clock named the Torre.
Diamond turning at Enfield
A new role for the Gurnos works Early in 1953 the No.1 factory
at Edmonton was closed and the whole of the manufacture and work
involved was transferred to Ystradgynlais. At the same time the
Mingware Company which manufactured watch cases, medals and medallions
was also transferred from Dundee. From 1953 onward, therefore,
the development of the watch case took place culminating in large
production of solid watch cases with their diamond turned techniques,
both chromium plated and gold plated for the use of the neighbouring
Anglo-Celtic Watch Company.
This period also saw the development of
new processes such as gong manufacture, incorporating tuning
rods and its associated techniques.
During this period of watch case development, the gold plating
techniques were introduced together with the anodising of aluminium
watch cases.
