Dial Color Response Study
Photography can distort dial color response on 178344-0017. Use a oblique interface view under neutral light, and lower the evidentiary weight if the apparent difference changes substantially with angle.
Bezel-Crystal Stack
Photography can distort bezel-crystal stack on 178344-0017. Use a oblique interface view under neutral light, and lower the evidentiary weight if the apparent difference changes substantially with angle.
Testing Crown-Tube Interface
178344-0017 should not inherit a conclusion about crown-tube interface from another watch in the same series. Map this exact Dark grey, 31mm and Stainless Steel configuration against the matching generation.
Lug Taper on This Reference
Photography can distort lug taper on 178344-0017. Use a diffuse frontal frame under neutral light, and lower the evidentiary weight if the apparent difference changes substantially with angle.
















David Thompson –
This was actually a pretty easy choice once I saw the different versions. What I like most is the overall design. For everyday use, it works for me.
