Type 5B

Description

Video First ever-mechanical watch to be perfectly readable under water regardless of the viewing angle: - Mechanical, Self-winding 36h power reserve - 41 jewels 25 gears 3 ruby ball bearings - 324 components in total - Designed to comply with the ISO 6425 ( diver watch norm ) - Full grade 5 titanium ( excluding the base movement ) - 10 ATM water resistant - 87 gramsDial Functions: - Hours, Minutes, Runner 90", Oil temperature, Rotating Bezel Innovations: - ROCS 5 ( patented complication module ) - 142 components - Convex grade 5 titanium bridges and discs ( 125 mm radius ) with 3 eccentric biaxial satellites inclined at 3 ( hours ) and 4,75 ( runner and oil temperature ) - 3D bridge architecture - Completely submerged in Oil ( 142 components ) - Driven by the minute axle of the base movement ( 2824-2 custom modified ) - Oil filled ( 37,5 ml ) - Bellow system ( to compensate for oil volume changes due to temperature variations ) - Magnetic transmission ( 12 micro magnets transmitting the minutes from the drybase movement section to the oilROCS module section ) - Magnetic shielding and flux concentration ( for higher connection power & movement protection ) - Hydraulic shock absorber ( to avoid an uncoupling of the magnets due to a shock - 5000G ISO norm ) - Two separate sealed of chamber architecture ( air & oil ) - Crownless ( winding and setup via case back ) - Locking system ( gasket compression system ) Relevance of the Type 5: - Only ever made mechanical watch that is readable under water regardless of the viewing angle. - Oil eliminates the internal mirror effect. All other mechanical diver watches must be viewed straight on. - Oil enhances the readability of the dial > main function of a watch. - Oil compensates for water pressure ( oil is uncompressible ) > light weigh watch for daily use ( 87 grams ). - Oil lubricates the ROCS components > less friction. - ROCS components are in suspension in oil. Lighter components > better precision.
