Ronda 705 caliber: dimensions and drop-in group

Used in: a slim no-date member of the Ronda 700 quartz family.

A slim three-hand quartz caliber at 26.20 mm x 2.50 mm, the no-date member of the 700 series. It shares the 715's footprint and stem and swaps with it within a matching dial.

Drop-in group: Ronda 700-series slim quartz (26.20 mm x 2.50 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.
