Designer

Marc Newson is an Australian industrial designer whose work spans Qantas cabins, Apple hardware and Jaeger-LeCoultre's Atmos clocks; his watch design reduces the object to pure geometry and legibility.

Historical significance

Citizen Promaster 39 mm Blue Quartz sits within Citizen's Promaster line, introduced in 1967. It carries the house codes established since 1918 — quartz tpt case, blue "grande tapisserie" dial and eco-drive solar quartz — and is one of the references collectors use to date the evolution of the collection.

Interesting facts

  • The bracelet tapers across its length, which is why the profile looks thinner on the wrist than the specification suggests.
  • The reference was originally planned as a one-year run and stayed in the catalogue for well over a decade.
  • Early production dials show a slightly different minute track, and collectors pay a premium for them.

Brand history

Citizen has spent more than 108 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Eco-Drive, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.

Kamekichi Yamazaki established Citizen in 1918, working from Japan at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Citizen calibre produced today.
