Sellita SW330-1 caliber: dimensions and drop-in group
The published footprint of the Sellita SW330-1 and which movements share it.
Used in: the Sellita caller-GMT automatic, the drop-in alternative to the ETA 2893-2.
Built to the 2893-2 GMT footprint at 25.60 mm x 4.10 mm with a caller-style GMT hand and date at 3. It carries four more jewels than the ETA (25 vs 21) and is the standard donor when a 2893-2 is unavailable.
Drop-in group: ETA 2893 / SW330 GMT footprint (25.60 mm x 4.10 mm, GMT hand). 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.
