Fit on 6–7 in wrists (6.5 in reference)
Fit: Low risk on a 6.5 in wrist. The 42.67 mm lug-to-lug and the 9.9 mm thickness are Union Glashütte’s figures.
The flat top of the wrist (usable span) is the width a watch can sit on without its lugs hanging over the edge.
| Wrist (approx.) | Union lug to lug | Thickness | Fit note |
|---|---|---|---|
| 6.0 in (152 mm) | 42.67 mm | 9.9 mm | Moderate risk: 42.67 mm is close to the flat top of a 6 in wrist (about 44.6 mm). |
| 6.5 in (165 mm) — reference | 42.67 mm | 9.9 mm | Low risk: 42.67 mm is under 90% of the flat top of a 6.5 in wrist (about 48.3 mm). |
| 7.0 in (178 mm) | 42.67 mm | 9.9 mm | Low risk: 42.67 mm is under 90% of the flat top of a 7 in wrist (about 52.1 mm). |
