Best known for their Grand Complications watches Patek Philippe masters the “Haute Horlogerie” and are arguably the best in the industry.
In 1989, to commemorate the 150th anniversary of the manufacture, Patek Philippe developed what is one of the most complicated portable timepiece in the world: the Calibre 89 with 33 complications but half a century ago in 1932 they had built the “Henry Graves Supercomplication” which had at that time 24 complications, including Westminster chimes, a perpetual calendar, sunrise and sunset times, and a celestial map of New York as seen from Graves’s apartment on Fifth Avenue.
For decades they did held the title of the most complicated watches built. Mastering their craft they perpetuated the skills and traditions to deliver in their current collection pieces of the highest quality.

*The present watch is the most complicated “Patek Philippe” watch available in their catalogue, the caliber took 9 years to develop.
Initially presented under a different metal with engraved case and special box, the reference 5175R was produced in only 7 examples to commemorate the 175th anniversary of the brand in 2014.
The “Grandmaster Chime” reference 6300G uses the same caliber as the 5175R but without the engraving and with a more discreet white gold case.
Over 1400 components house this double-faced-reversible masterpiece case, with a staggering 20 complications, namely  :

  1. Grande Sonnerie
  2. Petite Sonnerie
  3. Minute repeater
  4. Strikework mode display (Silence/Grand Sonnerie/Petite Sonnerie)
  5. Alarm with time strike
  6. Date repeater
  7. Movement power-reserve indicator
  8. Strikework power-reserve indicator
  9. Strikework isolator display
