Powerhouse of Timekeepers

Swiss watchmakers present their latest technical achievements in the newly redesigned Baselworld halls

HM Perpetual Moon

Arnold & Son presented the HM Perpetual Moon, a watch with a black guilloche dial highlighting a moonphase indicator with an 11.2mm three-dimensional sculpted moon, initially hand-engraved then copied for the series. An addition to its Royal Collection, the timepiece is inspired by the early part of John Arnold’s life and the watches he produced for court of King George III.

The 42mm ‘Modern’ model comes in stainless steel, while the 'Elegant’ model comes in 18k red gold with a blue guilloche dial and moon disk with golden stars. The 'Classic' model comes in 18k red gold with a cream-coloured dial and blue guilloche moon disk. The watches are powered by the in-house Calibre A&S 1512, a handwound moonphase with only a day’s deviation in every 122 years. One push on the corrector sets it again for another 122 years.

A sports watch with a black lacquer dial, Rolex’s GMT Master II Reference 116710BLNR has a two-tone bezel that for the first time comes in blue and black. While we’ve seen many versions of the GMT Master II before, this one is special because of its patented Cerachrom bezel, the special process required to create the two-toned ceramic. The bezel comes in one piece, and starts completely blue, and while still porous the black colour is added. The numerals are made of a thin layer of platinum, and the bezel itself is diamond polished. The watch comes in a 40mm stainless steel case, with appliques and hands in 18k white gold.
