Calibre 37.93

Notes

The 37.93 was created after 37.9, 37.9ABC, and 37.9M using the same basic components but a different bridge structure. It was conceived of as less expensive variant of the 37.9 for industrial and military applications. Its cost savings was primarily in the less refined finishing which at the time was a major cost in movement production. For instance its bridges were not chamfered like in other models in the 37.9 range.
