Although our focus is on affordable mechanical watches, we once in a while zoom in on watches that are either very special or plain beautiful. In this case, it is both. We have to admit that we didn’t make it to see this relatively new brand called Breva during last year’s Baselworld, but we wanted to make up for it this year at least. So we had the opportunity to look at last year’s introduced Breva Genie 01 and this year’s introduction of the Breva Genie 02.

The title of this article is one with a wink, as it refers to the Genie collection as being mechanical Smart Watches. Not your digital Smart Watch that has been recently discussed here by Prof. Dr. Jan Adriaanse, but a mechanical watch that is able to work as a real instrument like a barometer and a altimeter. Pointless? Perhaps, but so is reading time from a mechanical watch if that’s the topic of discussion. No, we love watch brands for coming up with original ideas and – as always – our main interest lies into the execution of such a timepiece. Truth to be told, it was quite refreshing to see a haute horlogerie watch manufacturer coming up with something different than a tourbillon. Or two.

With great precision, Breva is able to do a weather forecast with the Genie 01 and show altitude up to 5,000 meters (with the Genie 01 and 02). The Genie 02 works on the same principle of measuring air pressure to be able show the altitude, but according to Breva to a more precise level than the Genie 01.

The Breva Genie 01 (we got hands-on with the 4N pink gold version) is an awesome piece of machinery that has been developed with the help of by Jean-François Mojon/ Chronode. He again did the same for the Genie 02 (we got hands-on with the Terre model, crafted of G5 titanium). Both models have a crown at 4 o’clock that rotates 90 degrees to lock and unlock an air valve. This valve is used to allow a small portion of air inside the movement (or let it out) to equalize air pressure inside the case with the exterior air pressure. A red indicator on the dial marked ‘SEALED’ warns when the valve is open.

The screw down crown at 2 o’clock is used to rotate both the altitude’s precision-scale and large-scale to adjust for variations in air pressure, which affect altitude readings. Setting time is being down with the crown at 4 o’clock.

In the Genie 01, Breva uses an anaerobic barometer, in which one or more aneroid capsules (aneroid means ‘without air’) expand/contract with changing air pressure. The barometer and altimeter (air pressure changes with both altitude and weather) measure air pressure with two small aneroid capsules stacked one above the other – the top one being clearly visible on the dial side at 5 o’clock. The aneroid capsules in the Génie 01 were especially developed to Breva’s specifications to optimise their precision and use in a wristwatch. The capsules are made from a special non-magnetic memory-metal (Breva patented invention), which is lighter and stronger than aluminium and has twice the ductility of steel. The capsules are exposed for long durations to high temperature and pure oxygen to maximise thermal conductivity and oxidation resistance.

The Genie 02 is a bit different from the Genie 01 in that respect though, as its aneroid capsules were developed specifically for registering air pressure for altitude readings rather than barometric pressure, and are different to those used on the Génie 01.

As you can see, the movements seem to be identical, but the movement of the Génie 01 is a bit smaller (36mm diameter instead of 38,1mm) and consists of 405 components instead of 415 in the Génie 02.
