C65 Super Compressor
It’s not often you get to own a piece of watchmaking history.
But when you strap on the C65 Super Compressor, that’s exactly
what’s happening.
The rst super compressor mechanism was invented in the 1950s
by case maker Ervin Piquerez to protect diving watches from the
increased water pressure they faced as scuba divers went deeper.
The apparatus used that pressure to force the watch’s caseback
against its O-ring gasket – boosting water-resistance with every
metre descended.
In the 1970s, super compressors fell out of fashion. But now they’re
back – in an exceptional timepiece.
Your C65 Super Compressor is the rst genuine super compressor
diving watch in 50 years. Not only does its ingenious mechanism
increase water-resistance the further you go down but the
contemporary build quality and nishing is leagues ahead of the
original models.
Turn it over, and the exhibition caseback – a rst for a super
compressor – shows you the all-important compression spring
and diving-bell logo (the mark Ervin Piquerez used to denote
authenticity).
So, whether you’re a serious diver. Or just someone who appreciates
the art of horology, your new timepiece brings together on-point
retro style and watchmaking excellence in one unforgettable
package.
Wear it in good health!

For a superior water resistance your crown is of the screw-down
type. The crown should sit ush to the case (position 1) in order
to maintain water resistance.
• First unscrew the crown anti-clockwise from the case to position
2for winding in power. Wind in a clockwise direction to re-power
the watch. Your C65 Super Compressor has a maximum power
reserve of 38 hours when fully wound. Normal wearing will allow
the rotor to start re-powering the watch overtime after putting
on your wrist. After a period of non-use we recommend that
you manually wind the watch at least 20 times to ensure there
is sucient power in the watch before the rotor maintains the
power.
• Pull gently into position 3. This position is used for handsetting
and stopping of the seconds hand. For precise time setting it is
recommended to pass beyond the desired minute and to set
the hand backwards.

If using the internal bezel for a dive and let’s say the recognised
maximum “no-stop time” is 55 minutes, then in this example
(shown right) the time at the surface immediately before the dive is
10.10am. However the bezel marker is at the 12.00 hr position.
• Move the internal bezel with the 2 o’clock crown anti-clockwise so
that it aligns with the 10 minute position.
• You can now read that the 55 minute no decompression limit
will occur at 5 minutes past the next hour.
PLEASE NOTE:
It is always useful and best practice to make a note on a dive slate
before entering the water and to carry a set of dive tables should the
dive plan change during the course of a dive. A safety stop for 3 to 5
minutes at 15ft is recommended at the end of all dives. A safety stop
for 3 minutes at 15ft is required any time you come within 3 pressure
groups of a no decompression limit, and for any dive to a depth of
100ft or deeper.
