acquired the exclusive European rights to the TC87 movement platform from Seiko, who had patented the design back in 1997, and used it as the foundation for the 1887. TAG started with the Seiko 6S37 column wheel chronograph and adapted it to suit their needs, doing things like moving the balance wheel's position, flattening the movement out overall, and reconfiguring the main plate, bridge, and oscillator architecture.
If you're feeling skeptical at this point, bear with us for a second.
, while touting the 1887 as 100% in-house, has also announced publicly that it has a formal relationship with Seiko and is sourcing some less critical components for the 1887 from the Japanese brand due to Swatch Group restricting supply. All told, there are 22 suppliers of components for the 1887 and Seiko is the only one that is not Swiss. So while the "100% in-house" moniker might lead to you believe something a bit far from the truth,
has been transparent and provided information when asked about the 1887's provenance.
There are even a number of reasons why TAG Heuer building on this Seiko foundation to bring us the 1887 is a great thing. The proprietary, Seiko-conceived double pawl winding system is more efficient than a standard rotor winding system, and the column wheel system in this movement is extremely reliable and reactive. As mentioned above though, TAG did make some significant modifications to make the 1887 their own, one of which is the addition of their internally developed rocking pinion. To oversimplify a bit, this means the chronograph's seconds hand is always partially connected to the movement's running seconds gear train, so engagement is much faster and smoother.The chronograph functions in the standard way, with a pusher at 2 o’clock to start/stop and a rest pusher at 4 o’clock to restart the function. Each pusher moves with fluidity and precision, and the vertical chronograph hand responds with just as much ease, benefiting from the vertical clutch.
Good balance is achieved on the dial via a 3-6-9 configuration for the minutes, seconds, and hour-registers respectively. On the dial, you’ll also see a date aperture between 4 and 5 o’clock. The dial is available in two colors: black with white sub-registers and a "panda" version with white dial and black sub dials. The latter looks particularly crisp, with a bright red seconds hand adding some color to the bright white dial.
