TAG Heuer has just revealed its third outing with Hiroshi Fujiwara, the Japanese streetwear designer who founded fashion label Fragment Design (and is a vintage watch collector himself). The TAG Heuer Carrera Chronograph x fragment is based on the watchmaker’s signature “Glassbox” chronograph powered by the TH20 movement.

While it retains the same case and movement, the Fragment edition bears Mr Fujiwara’s familiar minimalist aesthetic, with the dial having undergone a monochromatic makeover that frees it of both colour and most of its numerals.

Initial thoughts

The new edition is the best of the three Fragment editions since it combines an excellent base in the form of the Carrera “Glassbox” with Mr Fujiwara’s aesthetic sensibility. I like the “Glassbox” design (though I wish it was slimmer), and equally appreciate the Fragment style, so the two together are an appealing combination.

I was a fan of the original Carrera Fragment, though less so of the second instalment, an Autavia that was too chunky and not monochromatic enough. Unlike the first Carrera that had a vintage feel, the new edition is distinctly modern and all the better for it. I think vintage reissues, particularly for chronographs of the vintage Carrera era, are overdone, so the contemporary style is a big plus.

At CHF8,150, this is priced close to the standard Carrera “Glassbox”, but definitely a more appealing proposition with the minimalist design.

Monochromatic minimalism

As with the earlier Fragment editions, the defining feature of the new Carrera is the dial. In typical Fragment style, Mr Fujiwara has given the dial a minimalist makeover. Gone are the numerals, leaving only hashmarks and squares. Admittedly this is not great for readability of the chronograph registers, but it certainly looks good.

Notably, the date disc has also been tweaked. It’s tone-on-tone with the dial in black with silver markings, while “1” and “11” have been replaced by Fragment’s lighting bolt logo.

The rest of the watch is standard Carrera “Glassbox”. The case takes inspiration from the 1960s Carrera, but with a highly domed sapphire crystal, no bezel, and matched domed flange under the crystal – hence the nickname “Glassbox”.

The dimensions are identical to the standard model, 39 mm wide and a little under 14 mm high. The thickness is noticeable, and probably the only weakness of the design, but it is a consequence of the TH20 movement inside.

Nestled against the sapphire crystal, the trademark domed flange of the “Glassbox” has been made into a key design element. The tachymetric scale is in white, giving it stark contrast against the clean black dial. And the tachymeter retains its numerals, unlike the dial.

Inside is the same TH20 movement that’s standard in the Carrera “Glassbox”, visible under a sapphire back printed with the Fragment emblem.

The TH20 the latest generation of TAG Heuer’s workhorse chronograph architecture and includes most features expected in a modern calibre, including a column wheel and useful 80-hour power reserve. The movement is a little thick, explaining the height of the case, but that will almost certainly be addressed with the next-generation calibre.
