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 first inner divers' bezel
incorporated with H micro gas tubes. The inner bezel rotates to measure
3
duration. In order to ensure optimal water resistance, the crown must be
screwed down before diving.

21. Patented crown protection system

MODELS: Models in the Engineer Hydrocarbon Series
A special crown protection system was designed and patented for the
Engineer Hydrocarbon series to guarantee its exceptional water resistance.
A protective plate is placed around the crown, which ensures the crown is
screwed back to its original secured position after time adjustment.
To unlock the crown protector, depress the button and rotate the bar counter-
clockwise. The crown can then be unscrewed for adjustment or winding.
After fully screwing down the crown, move the crown protector into place
by pushing down firmly until it locks.
