A replica watch with an in-house chronograph movement is something quite special. Until recently, even some well-established brands did not offer their own factory-built movement with a stopwatch function. It’s no wonder such movements are rare: a chronograph is a huge complication whose implementation requires enormous care and attention. For the longest time replica sports-watch brands like IWC and Breitling didn’t produce their own chronograph movements, either. But things have recently changed at these two companies: at the 2009 Baselworld watch fair, Breitling introduced its long anticipated in-house movement, the B01, and the first and only replica watch model to contain this movement, fittingly named the Chronomat B01. IWC presented its Ingenieur Chronograph at Geneva’s SIHH watch fair in early 2009, with an in-house movement that debuted in 2007 in the company’s Da Vinci chronograph.


The Ingenieur is only available with a single dial type and in two case materials (steel or rose gold). The Breitling Chronomat B01 is available with a wide range of different dials, with markers or Roman numerals, in steel or gold (or various combinations), and with a number of different straps and bracelets.

The other side of the coin? The IWC Ingenieur’s 45.5-mm case needs the width of a large wrist as a counterbalance. The watch overwhelms a normal wrist and doesn’t fit snugly. On a steel bracelet, it feels top-heavy and so must be worn tightly to keep it from sliding around. In contrast, the Breitling Chronomat B01 does not appear overly large despite its diameter of 43.5 mm, and it’s also more comfortable to wear. It lies snugly against the wrist, thanks in part to the supple rubber strap and adjustable strap extension integrated into the clasp. The Breitling clasp has a two-button deployment system that is attractive, easy to use and nicely finished. The rubber strap appears quite plain in comparison; luckily, the Chronomat also comes with a crocodile or calfskin strap or a metal bracelet.
The IWC Ingenieur Chronograph is also available with a crocodile strap or a stainless-steel bracelet. The bracelet can be adjusted without a screwdriver, and the single-button deployant clasp is surprisingly flat. However, the two hinged parts of the clasp are made of thin metal and shouldn’t be subjected to excess pressure when open. Both bracelet and clasp boast superb finishing: the bracelet’s carefully beveled and polished edges highlight the line finish on all other surfaces, perfectly matching the extraordinarily fine finishing on the replica watches uk case.

Breitling’s watch also includes both of these useful features. In contrast to the Valjoux 7750, these two manufacture movements allow the date to be changed right before 12 o’clock without running the risk of damaging the movement. The fluted crown on the Breitling Chronomat is easy to grasp and turn, and the pushers are also screwed. Although this makes using the chronograph function somewhat more awkward, it does provide greater protection for the pushers and increases the water-resistance of the watch to 500 meters. Unfortunately, you’ll have to press the button rather firmly to start the chronograph, due to the design of the chronograph levers. The Chronomat’s unidirectional rotating bezel has 240 ratchets and turns smoothly but should be easier to grasp.
Interestingly, the dimensions of the two movements vary only slightly. Each has an impressively long power reserve of more than three days. Plus, both movements are equipped with a bidirectional winding system and have an elegant column-wheel mechanism. But if you examine the movements (and you’ll have to remove the caseback from the Breitling to do this) the differences are immediately clear. While IWC uses the same automatic shock-protection rotor bridge as in its Ingenieur movement 80111, the Breitling appears somewhat more conventional. Breitling wins points with a patented self-centering system for the zero position resetting hammers, a calendar with an instantly advancing date, and especially for the modern vertical clutch that prevents the chronograph seconds hand from jumping when it starts. Breitling added a shock-absorbing escape wheel to make the Breitling replica watch more resistant to impacts. Another bonus: the movement includes an index-assembly that allows the wearer to quickly and easily adjust the watch’s rate to his or her preferred speed. Breitling also produces its mainplates and bridges in-house, and sets its own jewels as well.

The two movements are similar in their degree of decoration, with various finishes, perlage on the mainplate and polished screw heads. The cutouts on the IWC rotor provide a nice view of the movement, but few edges show beveling or polishing. Like the Valjoux 7750, IWC’s movement uses a rocking pinion for its chronograph clutch. This solution was developed in order to simplify the chronograph but has proven to be essential. The axis of the pinion is moved only on one side and causes the wheels to engage. IWC has created a special shape for the 240 teeth on the chrono-runner in order to minimize jumping of the chronograph seconds hand. Both copy watches contain stamped and polished levers, which remind us of those on the Valjoux 7750. Machined levers would have been better choices. Both movements therefore show a mixed bag of features, combining high-quality components with parts one usually finds in lower-grade movements.

Even though the replica Breitling uk watches run neck and neck in nearly all respects, there is a huge disparity in their prices: The price of the Breitling Chronomat B01 is close to the half of the IWC Ingenieur Chronograph. Even when both watches are equipped with a similar strap or bracelet, the IWC still costs much more than the Breitling. Prospective buyers for whom price is not an issue can decide solely in favor of the design that best suits their personal style.
