This is 100% true. Steel/SS/WG and even platinum are very similar in color in real life. Guys that are saying you can tell from the color alone is either a full time jeweler or talking rubbish there is NO WAY a normal person could tell or would know the difference. I've handled and worn WG/Plat watches for a long long time. The weight on a platinum though is crazy very very heavy.
In terms of the rep DD just get the BP in SS. Avoid the gold ones as you can never get the YG/RG ones exactly the same and as it attracts more attention your watch will be up to more scrutiny. I've owned 3 of the BP DDs now. 1 YG and 2 x RG and even though the color is ok it doesnt feel right (I have this perception of a gold watch needs to have the heft to it). Also the shine is not the same as the gens no matter in the sunlight or night time. The gens just shimmer differently.
If you want to avoid being "called out" and lets face it alot of you guys are pretending to be ballers am I right? just buy the SS models and pretend they are WG/Plat. And get the grey/lighter colored dials.
The chocolate/green and blue dials are not accurate at all.
Ended up with gen DDs anyway as at the end of the day the precious metal reps dont cut it for me. I'll stick to SS model reps from now.
