Durability of Watches/Movements Made of "Black Gold"

Oh, the sweet torment of research... :biggrin:

Some of you have seen me falling head over heals the Zenith Elite Ultra Thin in another forum...

Well, in the permanent quest of perfection [just another way of saying "still do not have the cash to spend, so I'm trying to keep me sane"], I have started investigating alternatives, like the oh-so-awesome-looking NOMOS Zurich.

One thing I notice on the website is that the movement is listed as "Movement: 蔚 (epsilon)鈥攎anufactory caliber with automatic movement, black gold". I did some reading on Wikipedia to find out that this is a 75% gold alloy with 25% of something else (depending on color variation).

I am posting to hear your thoughts on some of these questions:

- Is black gold alloy tough enough to last decades (pass onto next generation)?

- If price of the Zenith and the Nomos were equal: which one would you pick? Why?

- If you had to pick a dress watch and you had the choice - with or without date?

Thanks for your feedback :thumbup:

I prefer the thinness of the Zenith for a dress watch. I also like the subdial at 9:00. I do like the Tangomat series from Nomos quite a bit though and would like the Datum model as a casual watch. Balanced dial presentations are very important to me so if there has to be a date window I'd like it at 6 or 12. This seems to be more symmetrical with a subdial at 6:00.
What I'm having a hard time with is WHY Zenith (or anybody else for that matter) would use plating on a movement. Surely it can't be a superfluous sales gimmick!
Many companies coat the bridges & plates of their movements for decoration and prevention of corrosion. Rhodium and gold are the most common metals applied, but even copper has been used (Omega).
