Well, I am not sure much more than 2000 Duometre à Chronograph were produced... 300 in YG, 200 in WG, the rest in platinum... And not even sure 2000 were made! [nt]
RG Solid Dial - 13 RG Window Dial - 2 RG Grey Dial - 1 YG - 5 WG - 1 Plat Grey Dial - 2 Totally non-scientific non-statistically significant almost worthless guess but if we take YG availability as a reference point maybe they made 3-4x that across all RG...
