Chopard L.U.C All-in-One
Last June, I was able to handle an example of the very rare L.U.C All-in-One from Chopard.
The front dial of this two-sided watch is 'verdigris' and hand-guilloché. It features a Perpetual Calendar with a Big Date and a Tourbillon.

The
back dial features
five indicators (
equation of time,
day/night,
sunset,
sunrise &
7-day power reserve) and an
astronomical orbital moon phase.

The
complications are displayed in an
elegant,
clear and
attractive way. But, when you turn the
46 mm case on its side, the
monstrous 18,5 mm thickness appears and, unfortunately, these
gargantuan dimensions ruin the watch, imho.
The L.U.C All-in-One was first introduced in 2010 to celebrate the brand's 150th anniversary. The aim was, of course, to demonstrate the breadth and level of excellence of the Manufacture's expertise.
This first iteration, limited to 15 pcs in total, came in three variants:

Here's an
explanatory sketch of the original
dial design:

- Ref. 161925-5002 in rose gold: it's the reference of the particular example I was able to handle which was no. 10 of 10. Below are some additional photos taken by Monochrome:

Its specifications are: 33 x 11,75 mm - hand-wound - 516 components - 42 jewels - 28,000vph (4Hz) - four barrels (Quattro technology) - 7-day power reserve - COSC certified - Hallmark of Geneva

All in all (pun intended), the All-in-One is a
frustrating watch, whose attractive and beautiful elements are spoiled by
excessive dimensions (Patek Philippe's
Sky Moon Tourbillon ref. 6002, another beast which, unlike the All-in-One, includes a Minute Repeater, is 'only' 44 x 17,35 mm)...
Thanks for reading.
