De Bethune Demonstrates R��sonique High-Frequency Escapement Breakthrough
For the past several years, De Bethune has focused its research efforts on developing super-high-frequency escapements. Currently, most escapements operate at 18,000 to 36,000 vph (2.5 to 5 Hz). In 2006, De Bethune demonstrated an experimental 72,000 vph (10 Hz) silicon escapement. Their latest efforts involve engineers, watchmakers, and a physicist, all working to develop a next-gen escapement powered by non-mechanical forces.As De Bethune explains in its latest press release, taking traditional mechanical escapements beyond 10 Hz is not feasible due to reliability issues arising out of mechanical resistance and basic wear-and-tear problems.To advance the science of mechanical timekeeping, De Bethune is employing some non-traditional forces, namely synchronization between an acoustic resonator and a magnetic escapement rotor, operating in a mechanical watch. De Bethune has dubbed its discovery Horological R��sonique, and it is making its research available to the watchmaking community

5 things I learned from the 5740 (Nautilus PP) release...
1. That Patek is committed to keeping the Nautilus as a 40mm watch.With the last three new releases of the Aquanaut being at 40.8mm (5164), and then twice at 42.2mm (5168 and 5968) it is clear (at least to me) that ALL future Aquanauts are going to be larger than 40mm. The fact that they kept the 5740 at 40mm likewise makes it clear to me that the Nautilus will forever be a 40mm watch.2. That the 5712 has a water rating of 60m instead of 120m because of the 240 movement, not the pushers.Many people have said that the 5712 had a lower water rating than the other Nautilus watches because of the pushers to correct the moonphase and date. However, I always thought it had something to do with the 240 movement because the 5712 was the only Nautilus with that movement whereas the 5726 had pushers and still retained a 120m water rating. Even with advances over the past 12 years since the 5712 was introduced, the 5740 still came out with a 60m water rating. The 5740 and the 5712 are the only tw

Patek passion or crazyness?
Hi all, I wanted to know how you live your watch passion? When there is a piece you really love and want, regardless of the fact you have a big collection or like me limit yourself to 3-4, and you can get it new unworn at a great price, but it's not really the right moment, what do you do? Do you think ok it's not reasonable and I can find one later, or do you think it's better to borrow some money from a friend that you can give back in the next 3-4 months without any problem?Knowing that of course considering your financial status it's not super reasonable in any case, that at one point or another you might be uncomfortable financially because of this��I am asking this because as some might know my 2 favorites after my 5712 my 2 favorites are the 5167R and the 5726, I found a 5726 grey dial on strap, not my favorite, prefer bracelet but the strap would be nice if I have 2 Nautiluses, at a very interesting price for a new and unworn piece, basically 26,500K in euros, which is basically

Incoming from justrolexes!!!!
I would like to thank justrolexes to help me to get one of my favorite watch transaction was very smooth. i would definitely recommend justrolexes as one of the great sellers here on TRF!!!I would say this DD40 is one of the best looking dress watch out there. This definitely completing my collection for now. heres a couple photos along with my small collection hope y'all enjoy

7928 1962 Tudor Submariner Movement Fake or Real?
Hi there. Rotor Engravings throwing me off, despite movement looking spot on. Please help!
