[Album+timestamp](https://imgur.com/a/YVaqk8T) For sale is a 1957 Rolex Oyster Precision ref. 6422 (watch-only) on a 1982 Oyster bracelet. Looking for Zelle/Wire of $2749 for the piece. Very rare model from the late 50s/early 60s with a head-treated blued seconds hand (which is rare from Rolex). Only see a few instances of this on Chrono24 with comps ranging from $3400-4400. Watch is in relative good condition for it’s age with excellent time keeping. I’d recommend a new crystal due to marks across the face which is only prevalent in direct sunlight at certain angles and crown+gasket for water resistance if you’d like that functionality. Timing is very accurate (only a few s/d variance) and good amplitude as well. I have done several transactions on this forum and off-site. Please ask any follow-ups and thank you for your interest!
