MBFs Horological Machine No2-SV (Sapphire Vision)

May 19, 2022

Today, MB&F unveiled the Horological Machine No2-SV (Sapphire Vision) according to plan. Since early 2008, I am following Maximilian Busser and Friends with great interest and have reported several times on their extreme cool creations. My personal favorites are MB&F s (including Sage Vaughn) HM2 contribution to the Monaco Only Watch event and the recently introduced HM 2.2 BlackBox model that MB&F created together with Alain Silberstein.On the 6th of January, MB&F announced the upcoming introduction of a 25 piece only HM2, which is today, on January 12th of 2010. The HM2 SV edition gives away part of the secrets and inner workings of their Horological Machine Number 2 by using sapphire crystal to cover the entire front of the timepiece as you can see on the picture above.Sapphire s hardness is second only to diamond, which makes the whole top half of the case (the most exposed half) extremely scratch-resistant. This is a timepiece that will keep its good looks for a very, very long time. The 3.6mm thick sapphire crystal consist out of a top plate that has been constructed out of three separate parts. It takes up to 55 hours to create just a single top plate of sapphire. Actually, Stettler in Lyss (Switzerland) was the only manufacturer of sapphire crystals that accepted the challenge and managed to fulfil this task in a perfect way, so I guess they are worth mentioning here ??To ensure maximum light and visibility through to the movement, the two dials – minutes and date – are also in sapphire, sapphire disks lightly brushed to a perfect translucency ensuring full legibility of the polished silvered numbers while allowing maximum light through to the engine beneath.The movement of the HM2-SV, has been developed by master watchmaker J.M Wiederrecht, it feature an instantaneous jump hour, concentric retrograde minutes, retrograde date and a bi-hemisphere moon phase. One of the technical highlights of this timepiece is the highly energy-efficient jump hour/retrograde mechanism developed by Jean-Marc Wiederrecht, which uses his exclusive (and patented) asymmetrical-tooth gear wheels to ensure high precision and play-free functionality.The price of the HM2 – SV is unknown yet, but I am pretty sure it won t be in my personal collection any time soon. ??
