Felsa 4045


Felsa 4045Felsa 4045


Felsa was known for their high quality mens' watches movements, but they also made tiny form movements for ladies' watches, such as this rather simple caliber 4045.

This movement uses a traditional anchor escapement with Felsa-typical transparent anchor palettes, but the rest of the movement, the rather simple Trishock shock protection system, the missing regulator hand and the rocking bar winding mechanism below the that make one wonder, whether ladies' watches did not deserve the same quality as mens' watches.
