Caseback Profile
116758SA should not inherit a conclusion about caseback profile from another watch in the same series. Isolate this exact Black, 40mm and 18kt Gold & Steel configuration against the matching generation.
Testing Bracelet Taper
Instead of starting with overall appearance, examine 116758SA through bracelet taper. A axial macro can expose the relevant relationship while reducing perspective and reflection errors.
Perspective Error on This Reference
116758SA should not inherit a conclusion about perspective error from another watch in the same series. Evaluate this exact Black, 40mm and 18kt Gold & Steel configuration against the matching generation.
Testing Day Display
Use day display to challenge the internal consistency of 116758SA. The exterior configuration and the stated Automatic should tell a compatible reference story where this topic intersects them.
Mid-Case Mass
Mid-Case Mass gives 116758SA an independent evidence channel. Inspect repeated geometry or behavior against a same-generation genuine reference, using the Black and 40mm only where they directly affect this feature.


















Brian Thompson –
I was mostly wondering whether it would look as good in person. It arrived in good shape and matched my expectations reasonably well. I didn’t need much convincing after seeing it in person. It ended up being a good choice.
