This year is a vintage year and I've been leaning in the direction of Longines for a while now. There are other movements which have my attention but they are either made by a brand (Omega) that is already in my collection or are out of reach (IWC cal 88). No, this year I am looking for a solid example of the best mid-twentieth century watchmaking techniques in a manual wind movement.
Enter the Longines calibres 23Z, 12.68Z, 27M, and 30L
Ordered in size from smallest to largest, the 23Z is approx 23 mm in diameter, the 27M is a little over 27 mm, the 12.68Z is 27.5 mm, and the 30L is approximately 30 mm. This isn't important except for my preference that the movement should fill the case.
Alternatively, I have been developing an appreciation for vintage quartz calibres from the late 1970's through the early 1980's; specifically the Omega cal. 1333 and its non-chronometer variant. If any of these examples from Longines cannot be acquired, for whatever reason, I may choose to add another Omega to the box.
