Do you know of any watches with a hidden tourbillon? One that is invisible from the dial side? Of course, the Laurent Ferrier shown, Patek Philippe had several models, anything else? ...
The Lange 1 Tourbillon Perpetual, as well as the Datograph perpetual both have tourbillons hidden on the dial-side. I believe all other references with a tourbillon have them exposed on the dial side.
I understand it’s function to counteract gravity effects, but why do some pieces have this function “hidden” whereas most have a clear aperture showing the tourbillon.🤔
And exactly as Hussam said, I couldn’t imagine the marginal impact of tourbillons on time accuracy to be so significant for that sake alone. Therefore, the technical adornment factor makes the most sense.
...because most brands want to boast that a watch has a tourbillon (most customers want to show that off too). However, there are people and brands that do not need to prove anything to others 😉
