Heartbeat: Unique Piece Platinum Parallax Tourbillon by Grönefeld
by Ian Skellern
I’m just back (and still recovering) from an excellent SalonQP 2015, which looked better than ever to me.
The exhibition was awash with fantastic timepieces and we will look at more over the coming weeks and months, but here’s one that caught my eye: a unique piece Parallax Tourbillon in platinum with black dial and bright red highlights by Bart and Tim Grönefeld, two excellent watchmakers from the Netherlands who also happen to be brothers.
While Grönefeld is a relatively young brand launched only in 2008, the brothers’ family watchmaking heritage goes back a full 100 years.
The Parallax Tourbillon itself has a fairly enviable pedigree, having been awarded the prize for Best Tourbillon at the 2014 Grand Prix d’Horlogerie de Genève.
Bart and Tim put a lot of attention and effort into precision, so the Parallax Tourbillon has a large central second hand allowing the wearer to fully utilize its superlative chronometric performance.
As well as the dark dial and eye-catching red highlights, there are a couple of other interesting modifications to the movement in this unique piece that differentiate it from the core collection.
Usually (for Grönefeld at any rate; extremely rare for everyone else) the bridges of the Parallax Tourbillon are 100 percent unadulterated stainless steel with the varying types of fine finishing providing all of the contrast. However, for this unique piece parts of the stainless steel bridges have been treated with black ruthenium for even higher contrast.
Plus, instead of the usual circular graining on the tops of the bridges, this unique piece features straight graining.
And did I say that it’s a flying tourbillon?
And that the second hand always runs parallel to the balance cock?
And that you don’t pull out the crown to set the time but push it to select the function: time-setting or winding?
But that’s all bye-the-bye because the main reason I’m featuring this unique piece Parallax Tourbillon here is that it looks so bloody cool!
