I have had very good experiences with my gold reps, and still have to see their gold plating erased.
I bought a TT submariner to River about 7 years ago (supposedly one of those called "tripple wrapped") and it is almost as first day, even when i have polished gold parts maybe every 3-4 months since then (very carefully, of course).
Josh- Andrew,
please, post the followin watch as described in your web sites. I think it is a comparable stuff:
Movement: ETA 2892
Glass: zapphire with AR coating
Material: 316 stainless steel 18k white gold plated.
Water Resistant: yes
remarks: high quality deployant clasp
Thank you.
