The tonneau shape is the principal particular attribute of Richard Mille timepieces that comes to mind.
Extremely complex to understand, each Richard Mille tonneau-formed case addresses many separate machining and completing tasks. Throughout the long term the brand has culminated the manufacturing cycles of these cases accomplishing a genuinely extraordinary quality that you immediately see when you can handle them.
With the new RM 67-01, the normal case has been made – interestingly – in an additional level form, making it the most sleek model among all tonneau molded Richard Mille timepieces.
In spite of its smaller size, this case requires more time to be made than some other cases in the collection, amounting to almost 6 hours of unadulterated machining time, not including a long time of preliminary readiness, for example, the 68 diverse stamping tasks needed for the bezel, caseband and back bezel.
Simply consider that the machine tooling measure requires 8 days of changing the machines for the bezel, 5 days for the caseband and 5 days for the back bezel.
After completion of the machining stage, the watch case goes through brushing and cleaning, all executed by hand, at that point assembly with sapphire glass and sealants to go through a preliminary water opposition testing, prior to being disassembled and going through a last quality control.
Just by then, the movement will be encased in the 38.7 mm x 47.52 mm Grade 5 titanium case visible through the counter glare treated front and back sapphire precious stones.
The automatic movement CRMA6 is another type of just 3.6 mm thickness that was planned in house to prepare the RM 67-01 whose absolute stature is simply 7.75 mm. This skeletonised movement, beating at 28,800 vph with a force hold of 50 hours, highlights baseplate and connects in microblasted grade 5 titanium got done with a combination of dark and dark electroplasma treatment.
The skeletonisation of the movement incorporates likewise the enormous winding barrel, the going train and the high-proficiency platinum rotor.
The free sprung offset with variable latency ensures more prominent unwavering quality when exposed to stun and furthermore during the assembling and disassembling of the movement, for better chronometric results over the long run. Since there isn’t a controller file, the adjustment is performed because of 4 small adjustable loads found straightforwardly on the equilibrium.
The open worked dial incorporates a date show at 5 o’clock and a capacity marker at 2 o’clock. As the crown is pulled out, each position is shown by means of a hand permitting one to see what capacity is selected: W for twisting, D for date setting and H for hand setting.
The cost of the Richard Mille RM 67-01 will be declared next January at SIHH 2016 in Geneva. richardmille.com
