The Sentinel Special Edition of the Heavy Armor is hand-engraved by our engraver. Each
one's patent is unique in the world. In addition to the engraved Armor Plate set, the
Sentinel Special Edition comes with four different extra sets of Armor Plate sets and
four different colors second-layer Armor Plates.
Please note that as the watch is engraved by order, it takes 10 to 15 working days for
the watch to be engraved.
HEAVY ARMOR, THE DIVER WATCH THAT TRULY DARES TO BE DIFFERENT!
I am so excited every time I buy a new watch. I wear it every day and is so eager to
show it to everyone I meet. However, no matter how much I loved it, the love of it
drops as time goes by. It might end up sitting in a corner of my watch box after some
period of time. Up until now, you may only be able to add some freshness to the watch
by changing its straps. Or, if you have the knowledge and skills, then you can do some
modifications to it, but you are taking the risks of voiding the warranty, or worse,
damaging the watch!
THE WRISTWATCH THAT YOU WILL NEVER GET BORED WITH
Heavy Armor is another bold diver watch from DELTAt’s award-winning designer. Designed
with the concept of change in mind, Heavy Armor dares to be different! Besides being
cool and special, with its changeable armor set system, you can easily dress it up with
different sets of bezel plates that give it new looks and feels anytime you want to! We
have initially rolled out four armor sets, The Diver, The Skeleton I, The Skeleton II,
and The Diver II. More designs and materials will be added to the collection. You can
even mix-and-match the plates with different sets to give the watch a look that is
unique on your wrist. Everyone loves being unique, right?
Heavy Armor is also a top notch diver watch. It has everything a diver watch needs,
plus the quality and craftsmanship you would expect from DELTAt. To be considered a
diver watch, the watch needs to meet the following requirements:
Unidirectional bezel – to time the diving session. It has to be unidirectional in
anti-clockwise, so that even if the bezel is accidentally turned under water, the
end of session time can only be shortened instead of lengthened. Indicated Time
Passed is more than Actual Time Passed, so you have to go back to the surface
earlier. On the other hand, if the bezel is turned clockwise, due to the starting
time being pushed forward, the end of session time is postponed, and it is lethal
as the supply of oxygen may run out due to thinking that there is extended time
left for the session.
Clearly distinguishable minute markings – every minute passes is crucial in a dive session.
Luminous index and hands – ensure adequate readability at 9.8 inches in total darkness.
Water resistance – at least 100 m / 330 ft / 10 ATM water resistant.
Heavy Armor meets all of the above requirements and it doesn’t stop there.
Water Resistance – Heavy Armor is water resistant to 1000 m / 3,300 ft / 100 ATM!
With its automatic helium escape valve, it is even suitable for saturation diving.
Material – Heavy Armor uses 316L Stainless Steel as its case and bottom cover's
material. 316L Stainless Steel is a surgical grade material. Not only because it is
very hard and corrosion free, it contains much less nickel as to not trigger an
allergic reaction to sensitive skins.
Movement – in order to be a collectable, a wrist watch must use a mechanical
movement. Mechanical movements not only represent the inheritance of watchmakers'
tradition, they are the essence of over 200 years of watch history. You can't
imagine how difficult it is to measure one second precisely by pure mechanical
instruments, especially if it compares to electronic devices. This craftsmanship
alone is considered as a form of art. Heavy Armor uses the Japan Time Module
(Seiko) Automatic Movement Cal. NH35. The Japan Time Module (Seiko) Automatic
Movement Cal. NH35 also features the hacking seconds Function, which allows you to
set time precisely up to the second.
Crystal – Heavy Armor uses Sapphire Crystal. Sapphire Crystal is the second hardest
natural mineral on earth. Rated 9 at the Mohs Scale, only after diamond. A material
will be scratched only by materials that are harder than itself, so the chance of
Sapphire Crystal being scratched is very low. It has become the standard of luxury
wrist watches.
Straps – Heavy Armor comes with 2 sets of straps. Special Nylon strap and Rubber
strap.
Packaging – Heavy Armor’s case is made from ultra-high impact resistance plastic.
Equipped with O-ring seal and automatic pressure equalization valve, it is chemical
resistant, corrosion resistant, airtight, watertight, and dust proof. Together with
the interior foam, it provides perfect storage and protection for the Heavy Armor.

Saturation diving is a diving technique that allows divers to reduce the risk of decompression sickness when they work at great depths (up to a few hundred meters, which is much deeper than scuba diving) for long periods of time. In saturation diving, the divers are subject to a pressurized environment. This may be maintained for up to several weeks, and they are decompressed to surface pressure only once, at the end of their tour of duty. By limiting the number of decompressions in this way, the risk of decompression sickness is significantly reduced.
The pressure is slowly reduced during the decompression, and this is when some of the earlier, standard dive watches started to show problems. As the pressure reduces, internal pressure in the watch builds up due to its effective sealing, and the watch’s crystal would sometimes pop off.
Doxa and Rolex started working on addressing this problem at around 1967, and released the first helium escape valve for the Rolex Sea-Dweller at 1968. It is called helium escape valve because the breathing gas mixture used contains helium, and when in the decompressing session, it is used for releasing the helium inside the watch.
Old/manual helium escape valve has to be operated manually. Thus, you have to open the valve of the watch manually during the decompression session in order to release helium from the watch. Heavy Armor equipped with an automatic helium escape valve, which operates automatically. It opens automatically when the pressure inside the watch is higher than its surrounding environment.
