I have some, but all Zenith (surprise, surprise) Cal 133 Cal 133.8 133.8 Chronometre 40T Chronometre El Primero G582 Cal 106 Not sure if this counts, but my Elite HW Chronometre with power reserve
Forgot to add the Chronograph Suisse but does "sheet gold" really count? - it's effectively gold capped without the base metal.
Only one solid 18k. Lemania 3015 HW. Picked up for peanuts as it was auctioned as GP. The rest are filled, plated or capped. I'm normally a steel guy.
I'm normally a 'steel guy', too, but then, a year ago, I got this: 18K cal 146D ...and then these: 18K '61 cal 341 18K '66 Pulsations cal 342 14K '53 cal 23Z 14K '50 cal 22AS 14K '50 cal 22A 10K '61 cal 350 ...followed a few months later by: 10K '66 cal 343
Yet, I wasn't over. earlier this week (seller's pics): 18K '60 cal 551 Thank you, again, @cristos71 ! Oh, almost forgot! My other gold Omegas: 14K GC '53 cal 344 14K GC '58 cal 505
