SMITHS - Made in Great Britain - Smiths Industries Limited - Two (2) Jewels Unadjusted. Mechanical Mantel Clock with floating balance.
This clock came into the workshop not working, both mainsprings are fully wound up!
Smiths licensed the floating balance from Hettich but by 1960 had developed an improved version capable of easier adjustment using an external calibrated adjustment.
From about 1966 the name "Smiths Industries" appears on some models.
Time to remove the movement from the case!
The Floating Balance
Completely disassembled the movement.
While deconstruction of movement every pinion was stuck in a bush, due to congealed oil! (Not been serviced for a long time).
On the first inspection of the movement it is soon revealed that one of the mainsprings has popped out of the barrel, was the clock dropped?
Deconstruction of the movement
Remove both mainsprings from their barrels.
Old spring which is concerned which caused the barrel lid to co
me off, and the new mainspring
The other (Time) mainspring was "set", so ordered a new one.
Both new mainsprings fitted into barrels
Cleaned all the parts and reassembled the movement and it runs perfectly.
Video of the clock striking 10
How do you remove the gear that stops the removal of both spring barrels?

Their is a circlip to remove on the wheel on the other side of mainplate. When that and the diped washer and wheel removed, you can then pull the main wheel out through the plate. The main center wheel was left in place on this clock as there was no play in it.
