Donor movement for the Ronda 705
Which movement drops into a Ronda 705 case, and what has to match beyond the footprint.
Drop-in available. The Ronda 715 shares the Ronda 705 footprint (26.20 mm x 2.50 mm, centre seconds, no date, slim) and is the standard donor.
The Ronda 705 sits in the Ronda 700-series slim quartz (26.20 mm x 2.50 mm) group. The Ronda 715 share its casing diameter, height and calendar layout, so a case and dial built for the Ronda 705 accept them with the correct dial and hands.
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.
