Which of these two wonderful Vacheron Constantin watches appeals to you the most?

  • Historiques Ultra-Thin 1955 in rose gold, ref. 33155/000R-9588 with hand-wound caliber 1003. Dimensions: 36 x 4.13 mm
  • Mercator in yellow gold ref. 43050 with a solid gold dial representing a map of Europa, Africa, Asia & Terra Australis. The watch is powered by automatic caliber 1120/2. Dimensions: 36 x 8.5 mm
I personally prefer the Ultra-Thin because of its hand-wound caliber 1003 and its incredible fit on the wrist.

Best, Emmanuel

Even if the 1120 is a great movement,

I wish the Mercator had a hand-wound movement (or at least a beautiful rotor). Best, Emmanuel

The movement of the 1955 is tiny...

...the movement of the Mercator fits well. And at 8.5mm the watch is more than thin enough...

Tiny but gorgeous. The presence in real life is simply stunning.

It feels premium, not at all tiny. Whereas the rotor of the Mercator doesn't feel to be up to the level of the dial and case, imo.

We agree on the rotor...

...it is very pedestrian...

Mercator

I like the finishing on the thin but movement too small. The unique dial time indicator and dial patterns push Mercator over the edge. I like the strap here too.

I definitely understand your preference.

I just wish the Mercator had a hand-wound movement or at least a beautiful rotor. Best, Emmanuel
