TAG Heuer Monaco has always been linked to racing. The patented belt-driven Monaco V4 has crossed the finish line back in 2004. TAG Heuer Monaco V4 Tourbillon (aka Monaco V4T) comes in time to celebrate the 10th anniversary of the famed Monaco V4. Related Replica TAG Heuer Monaco V4 Tourbillon.
The first things to notice are the two v-shaped bridges. These bridges are made from steel, bevelled by hand, fine-brushed and finished with a black coating. The largest one is holding the belt wheels. When you take a closer look at the belts, it shows how incredibly tiny these actually are, with a thickness of 0.07 mm only. The tourbillon cage is located at the 9 o’clock position, placed underneath the belt wheel thus making it less visible. It makes a full rotation in one minute.
TAG Heuer Monaco V4 Tourbillon uses a square case slightly larger than the original, at 41mm wide. I believe that the original Monaco V4 came in a 39mm wide case. Personally, I love the shape of this case, and the black-coated titanium with its glossy finish makes it look like an Imperial ship out of Star Wars, or something that Darth Vader would wear. Over the dial is a beveled sapphire crystal with AR coating and the case is water resistant to 50 meters. The slight cushion-shape of the case is what has helped the Monaco family watches look good on wrists for so many years. I mention this because, while I like the idea of square or rectangular watches, very few of them end up looking good on one’s wrist.
TAG Heuer Monaco V4 is powered by a linear mass, which is visible on the back side of the watch. Made of tungsten, a metal that is most known from it’s use in light bulbs. This lingot shaped weight moves up and down on a rail system, located between two pairs of barrels that are angled at ± 13 degrees, like the cylinder of a racing engine. Each set of barrels is linked by a single belt, with internal steel reinforcement wire.
