Many purists feel that movement and case design should be in harmony, and I share that belief.
A round case should house a round movement and a rectangular case should ideally house a rectangular movement. Similarly there are those that feel that movement and case size should be a proper marriage as well. We see this principle frequently violated however by many of the finest watchmakers, I can only assume for reasons of economy. Why else would the 5196 at 37mm and 5123 at 38mm contain the same movement designed for a 31mm case? I suppose a solid caseback often solves the problem but for the purist it only hides the reality.
Movements that are appropriately sized and shaped for their cases are special, and this piece has both.

Some early versions of the 5119 had casebacks secured with screws, while later models had snap backs. Not sure when or why they made the change.
... that one can easily overlook it.
Thanks for the link.
