Who makes real gold reps?

[JMS1988]

They exist and have existed since decades. None, or none of them that i know of are produced in substantial volume though, so you might have a problem finding one right now. I've seen and handled a few of these. They're generally a bit of a disappointment, as even though they use solid gold they're not super reps, definitely not by today's standards. They're also lighter that gens, sometimes the gold color was off as well, particularly when substituting 18ct gold with lower-carat alloys with too much copper or silver.
They're generally a thing of the past, when gold price was cheaper and so was the craftsmanship. Many of these watches were made locally by jewelers for people who didn't mind paying for gold, but couldn't justify paying 5 times the metal price to get a gen Rolex Day-Date with it, Daytona copies were quite common as well even though none of them was in any way comparable to Noobs and Cleans of today.

I've seen them for sale locally in Europe and i've seen them on American craigslist as well. Like i've said, these are individual units so i won't give you a direct link to a TD

There are also many solid gold homages, often carrying the brand name "Geneve", such as this one: GENEVE 14K Yellow Gold Swiss Automatic w/ Day/Date Feature - Rolex | Barnebys
If you'd replace the dial, movement and crown you'd have a reasonably convincing Day-Date rep - but don't, as it's much too light to pass off as a gen anyways, in fact it feels way more cheap and flimsy than stainless steel BP reps of the same model

Also, a few of our TDs carried solid gold reps and even listed them on their websites, i think Andrew still has a $9k solid gold President rep in the product catalogue, even though it's discontinued and has been for some time now
