Historical significance

Arnold & Son Globetrotter 39 mm Slate 18k sits within Arnold & Son's Globetrotter line, introduced in 1959. It carries the house codes established since 1764 — 18k white gold case, slate grey dial and in-house automatic with 22k gold rotor — and is one of the references collectors use to date the evolution of the collection.

Interesting facts

• Early production dials show a slightly different minute track, and collectors pay a premium for them.
• The reference was originally planned as a one-year run and stayed in the catalogue for well over a decade.
