DOUBLE TOURBILLON AVENTURINE WHITE GOLD

Exhibiting superlative craftsmanship and watchmaking prowess, the Double Tourbillon Aventurine White Gold by Arnold and Son introduces a spectacular arrangement of two tourbillons each regulating their own time zone, displayed upon pristine white opal dials against a background of shimmering aventurine. An exclusive Unique Piece for the discerning collector, the watch is presented in a beautifully styled 18ct white gold casing.

The technical highlight of the Arnold and Son Double Tourbillon Aventurine White Gold is its complex arrangement of two independent tourbillons, each of which regulates its own time display. Created as a reference to marine travel in the 18th century when a ship’s captain relied on his marine chronometer and astrology for safe passage, each time display can be set accurately and independently to within a minute, giving added usability in time zones offset by 15, 30 or 45 minutes.

Both time zones on Arnold and Son's Double Tourbillon Aventurine White Gold are displayed on beautifully executed white opal dials each rimmed in gold. The local time is displayed via Roman numerals at the 12 o’clock, with the reference time via Arabic numerals at the 6, and the effect of the blued, openworked hands against the purity of the opal is superb. The dial plate is of a sliver of aventurine, with its naturally occurring sparkles adding further depth and beauty, and perfectly placed to promote equipoise, generous apertures have been cut into the glass to display the twin tourbillons with the outline giving the arrangement a clover-like shape form.

At the heart of this impressive display is the manual-winding double tourbillon A&S8513 calibre, which has been meticulously finished with sunray Côtes de Genève, circular graining, snailed decoration on the barrels and hand-polishing and chamfering and gold tourbillon bridges. Ensuring further reliability, the two separate gear trains and tourbillon escapement of the Double Tourbillon White Gold Aventurine are powered by two mainspring barrels giving 90 hours of power reserve when fully wound.

Arnold and Son's Double Tourbillon Aventurine resides in an 18ct white gold casing sized at 43.5mm across. Beautifully polished, it carries neat curving lugs and a trim bezel, and is fitted with crowns at the 2 and 7 o’clock positions to enable independent adjustment and winding of the two time zones.

Presented as a Unique Piece, the Arnold and Son Double Tourbillon White Gold Aventurine wears on a hand-stitched alligator leather strap secured with an 18ct white gold clasp.
