I cannot help with Raffles, but gold plating is relatively easy. However, due to the expense, unless you have multiple watches to plate or plan on going into the plating biz, it is usually more cost effective to have a jeweler perform the gold plating for you. You are likely to spend close to $1k on a decent gold plating system & alot less to pay a jeweler who already has the equipment.
As always, because ALL reps contain inaccuracies & different people have differing sensitivities to different inaccuracies, it is impossible to give you an answer. However, if you have not already done so, you might find this thread helpful in making your own determination.
I can understand why you did not install gen (white gold) hands on your beautiful Zenith Daytona. Gen handsets are VERY pricey, often costing thousands, which is why you should click here (& do it soon!). &, if you had a profitable Xmas, you should click here too.
