Watch movements (ETA / Miyota)ETA 2824-2 and Miyota 8215 are the two movements that service almost every Swiss-style automatic watch. Buy by caliber number, not by brand claim.
Case back openers + toolsA screw-back opener and a 7-die crystal press handle 90% of watch work. Don't improvise with pliers — scratched case backs hurt resale value significantly.
NATO straps (nylon)NATO straps are the honest choice for vintage daily-wearers — they're replaceable if worn and protect the case from scratches at the lugs. Buy in 3-packs.
Spring bar tool setA proper spring bar tool prevents slip-and-scratch. Bergeon 6767 is the professional choice; the $15 alternatives all work but the tip quality varies.
Watch winderSingle or double winders are enough for most collections. Look for variable TPD (turns per day) settings — Rolex and ETA calibers have different requirements.
