The Breguet Marine Tourbillon Équation Marchante
In 2018, the Marine collection got a fairly extensive design refresh, but this particular watch largely follows the same design cues as it did when it was launched in the previous year. While the 5887 retains the design language of the 2017 model, it feels like a quite different watch, with a new rose-gold case, slate-grey dial, and rose-gold markers and hands, which give it a more approachable (although certainly still obviously luxurious) feel.

When the first platinum version of this watch launched, the aesthetics (which, to be fair, are what most watches sell on) were to me less interesting than what it represented in terms of mechanics. It's both a very new-fangled and a very old-fashioned watch. On the one hand, you have the peripheral rotor system, as well as the sapphire-crystal, mounted cam for the Equation Of Time. On the other hand, you have the tourbillon and the Equation Of Time, both of which are about as old-fashioned as a complication can get. Replica Tag Heuer
The Equation Of Time is a challenging complication to understand, partly because it does not correspond to anything most of us encounter in our daily experience of time. One way to think of it is to think of what constitutes noon. Intuitively, noon is when the Sun is at its apex, its highest point in the sky. This, in turn, should be understood as astronomical observation, and one made with a certain devotion to precision. Exactly when the Sun reaches its apex – its zenith, or the highest point in the sky as observed from a particular point on Earth – will vary depending on your longitude and latitude.
If you are in a given city, noon, at least based on looking at the Sun, is not going to be at the same time as it is at a city 20 miles east or west. If you are getting noon off a sundial in your garden, you get a different moment for noon than someone located somewhere else. This is fine, until you have things like a national rail system. If you are trying to get trains to run on the same time, you have to have a time standard that is the same for all stations in a given area: at that the point, you need an average, or mean, time for all the stations, be they in London or Liverpool.
This is where the Equation Of Time comes in. The EOT basically tells you the difference between your local solar time and the mean time for your location. If you know, for instance, that the EOT for a given day is plus five and a half seconds, you can set your clock, which must record a day of 24 hours, to the correct mean time for your location. Once you have the correct mean, or average, time for your location, you can then further adjust the clock to the civil time for your time zone.
The Equation Of Time is meaningful to horologists, clockmakers, and watchmakers but there is perhaps no other complication that is more divorced from everyday experience. That it is the difference between local true solar time and local mean time is hard enough, but when you add the difference between local mean time and civil time in an entire-time zone, most of us just check out. Still, it is a beautiful complication, in that it exposes the somewhat arbitrary and man-made notion of civil time in a given time zone (EST, CET or what have you) and what we actually see in the sky.
The easiest way to show the Equation Of Time is to put a sector on the dial that shows, plus or minus, the difference between civil time and true local solar time.
However, a more sophisticated solution is to have a hand on the dial, co-axial with the minute hand, that follows the minute hand around the dial and shows, at a glance, how far behind or ahead the Equation Of Time is for a given day. This is the so-called Equation Of Time merchant.
The 5887 in rose gold has all the technical virtues of the original platinum version, but it feels to me more approachable. The platinum model from 2017 was a bit too much – slightly cold, slightly too much an obvious public gesture of ostentation; you may say that rose gold is more obviously ostentatious, but it is also more traditional for a high complication and just feels, to me, like a watch that welcomes you in and encourages inquiry. Watching the kidney-shaped cam for the Equation Of Time make one stately revolution per year is a common intellectual pleasure to both, of course. It's one of the most impractical watches I have ever seen and absurdly expensive, as what is not in high-end watchmaking these days. But it is a pretty thing for all that, and I would not mind at all to spend a year watching that cam, which encodes the difference between real astronomy and the abstractions of industrial civilization, make a single rotation.
