Miyota 9075 caliber: dimensions and drop-in group

The published footprint of the Miyota 9075 and which movements share it.

Used in: the Miyota true-GMT (traveller) automatic, in affordable GMT travel watches.

A 90-series-based true/traveller GMT at 26.00 mm x 4.92 mm with an independently-set local hour hand and a 24-hour GMT hand. Taller than the time-only 9015, it needs a GMT dial and hand set of its own.

Drop-in group: Miyota 9075 true-GMT footprint (26.00 mm x 4.92 mm). Matching diameter and height is necessary but not sufficient. A donor is only a true drop-in when the dial-foot positions, hand-hole sizes, stem length and calendar layout also match. Two movements can share a case and still need a new dial, re-broached hands or a cut-to-length stem.
