Silver Half-Hunter Swiss-Made Pocket Watch, Circa 1927.

This is an item of sentimental value to a local Widowed gentleman.
It means a great deal to him as a running movement. Regrettably,
The minute-wheel in the forth picture , is damaged beyond repair and so
needs to be replaced. Thousands of watches similar to this one , were made but almost every maker, chose a different sized wheel.
The size required here is precisely 9.25mm Diameter . Teeth: 36.
The inner wheel : 10 Teeth. Although the Caliber of the movement is 40.8mm, it does NOT indicate , that the minute -wheel will be necessarily
either bigger OR smaller than the size i have stated. Please can you help?

The item, bought in Swansea, South Wales, found its way to South Africa
and as a military Time-Piece to this gentleman`s family.
