Advice needed on Day Date lapis dial

[Andrejkka]

Hello! I would be extremely grateful for any advice on a stone-dial Day Date. I have been looking for a lapis dial for a long time and I found one in great condition, but I am unsure about the dial. Unfortunately, I cannot see the watch in person and I have to make a decision based on photos only (attached). The watch is yellow gold, but the lettering on the dial seems to be silver, and I am unsure if the crown symbol on the dial is white gold or yellow gold. I would expect everything to match the case, so I find it odd. The other question I have is why is there T SWISS T on the dial when there is no lume on the watch. Could anyone advise if this is all just normal variation or a problem.
Many thanks!
