5.13 Rotating bezel
Most of the models within the Engineer Hydrocarbon series feature an
unidirectional rotating outer bezel incorporated with luminous paint for
night reading. The bezel is painted with 60 minute elapsed time notation.
The 60 minute bezel can be used for timing events by setting the zero dot
at the current minute.
The bidirectional rotating outer bezels of the Engineer Hydrocarbon GMT
models are painted with 24-hour GMT notation. To use the GMT bezel,
simply turn the bezel until the local hour matches the GMT hand.
The Engineer Master II Diver models feature the rst inner divers’ bezel
incorporated with H
3
micro gas tubes. The inner bezel rotates to measure
duration. In order to ensure optimal water resistance, the crown must be
screwed down before diving.
5.15 Mu-Metal & Carbon composite case
Carbon provides excellent resistance to scratches and impacts, and only
weighs about 50% as much as the steel customarily used for watch cases,
a signicant gain of lightness on the wrist. Mu-metal is an alloy of nickel,
iron, copper and molybdenum with very high magnetic permeability, which
gives anti-magnetic properties far superior to the soft iron usually employed
in watchmaking. The revolutionary structure of the mu-metal and carbon
composite case with textured appearance allows for an extremely high
protection (80,000A/m) against magnetic elds.
5.14 DLC & TiC Coatings
Diamond-Like Carbon (DLC) and Titanium Carbide (TiC) coatings provide
superior scratch resistance and longevity. Metals coated with such material
exhibit impressive hardness, low friction, high resistance to wear, and
even electrical insulation. Research shows that DLC and TiC coatings
dramatically improve the performance and life of any material.
