Omega 166.002 Speedmaster Companion "Tropical Brown" Dial Gold Plaque Case?

Are you referring to the dial type and hands or the fact it’s in a gold capped case?

It looks fine to me.

It’s actual a technical dial, not a Speedmaster companion.

S
Speedmaster companion dials are different. No crosshair etc. several threads on the subject on this forum for you to read.

Do you know the dial is brown? It looks black to me, but even if it is, it’s just natural aging of the black finish.

The white seconds hand is fine. I would think gold coloured hour/minute hands would be more appropriate for a gold case but I don’t know for certain.

Lots of examples of technical dials in gold capped/filled cases. There’s even advertising with text saying available in steel and gold plated. However, these are usually in seamaster 600 guise. That could be because most technical Seamasters are SM600’s with the auto version 165.002/166.002 being less commonly seen

It could be that there was no gold plated/filled 166.002 technical dial from the factory but that would be slightly unusual. I would expect it was a legit variant. However, I would expect gold tone hands.
