Table of foreign calibres used by MST

Roamer used some foreign calibres when they could not meet the demand for a specific product with an in-house calibre. This is most clear with the automatic movements - with both the Felsa 279 (no MST number), which was the first Roamer Automatic watch from the start of the 1940s. and the MST 441/452 which were modified versions of the Felsa 4002/4007 movements and fulfilled the need for an automatic with date mechanism at the start of the 1960s. Other examples include the use of the thin Peseux movements in very thin dress watches such as the Pall Mall. All the following mappings of calibres come from MST documentation or observed directly from calibres. After the death of Ernst Meyer in 1967, who was the last of the sons of Fritz Meyer, outside calibres were used much more frequently.
