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:

A white gold variant, ref. 161925-1001 :

A gem-set bezel white gold variant, of which Kong posted some great photos here:

And a rose gold variant, ref. 161925-5001 :

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

In 2018, the L.U.C All-in-One's dial was redesigned and two new references were introduced, each limited to 10 pcs:

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:

The movement powering this beast of a watch was first referenced as calibre L.U.C 4TQE (probably for '4 barrels', 'Tourbillon', 'Quantième' and 'Equation') and later became L.U.C 05.01-L.

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.

Key Points from the Discussion

The L.U.C All-in-One, despite its superlative complications, suffers from aesthetic shortcomings, including a disproportionately large tourbillon bridge and a small date display, which detract from its overall beauty.
For some collectors, the substantial dimensions of the L.U.C All-in-One, with its 46mm case and 18.5mm thickness, are not a deterrent but rather an appealing characteristic, signifying a robust presence on the wrist.
The author, quattro, acknowledges that if one accepts the premise of a large watch, an additional millimeter in thickness might not significantly alter the perception. However, he suggests that for such substantial pieces, a 'wilder' and more bespoke option like the Patek Philippe Ref. 5011T with its hidden tourbillon and minute repeater might be a more compelling choice.
The L.U.C All-in-One is seen by some as a magnificent display of technical prowess, but its 'unforgiving proportions' ultimately reduce it to a decorative item rather than a wearable timepiece.
There's a general consensus that the second-generation dials of the L.U.C All-in-One are aesthetically exquisite, particularly the verdigris dial paired with a rose gold case.
Chopard has recently begun to reduce the size of its watches, leading to hope among collectors that the L.U.C All-in-One might eventually be re-released with more wearable dimensions.

I absolutely love the rose gold variant, ref. 161925-5001

Size, as in too big, is never an issue for me when it comes to watches. Some of us like knowing that we have something substantial on the wrist. 18mm thickness? 46mm case? Bring it on! Ha ha. Thanks for sharing such lovely pics too.

I’m glad you like it, Ron!

It’s definitely substantial and, if one has the adequate wrist and body size and enjoys a big watch, it’s a piece to consider. Aesthetically, I like the second gen dial very much, especially the verdigris with a rose gold case. Best, Emmanuel

I couldn't agree more with you on this one....

What a marvelous showcase of technical prowess, only to be deduced to something akin to a decorative item as a result of its unforgiving proportions.... Thank you very much for the excellent pictorial, cheers, Filip

Thank you Filip!

Too bad, indeed. Especially as I like the verdigris dial of the watch I was able to handle. These past two years, Chopard has started reducing the size of its watches. Hopefully the All-in-One will be put on a diet someday… Best, Emmanuel
