Stainless Steel 316L
All cases made of Stainless
Steel 316L type is a low oxidation metal and more resistant
tro corrosion and pitting than conventinal
nickel chromium stainless steel such as 302-304
It has the following characteristics:
- Higher creeo resistant.
- Excellent formability.
- Rupture and tensile strength at high temperatures.
- Corrosion and pitting resistant.
Movements:

Date corrrector,
stop second device, regulation system ETACHROM.Anti-shock system
INCABLOC.
Dials:
High performance Phosphorescent Pigments SUPERLUMINOUS. Also called "photo-luminiscent"
or "afterglow" pigments. These are non-radiactive and non-toxic
alternative for iluminating markings on time-pieces dials and hands
in the dark. Selected grades of new chemical compositions have up to
a 100 times better brightness than previous zinc sulphide materials.
These pigments operate like a light battery. After sufficient activation
by sunlight or artificial light, they glow in the dark for many
hours. Larger markings are visible for a whole night. This
activation and subsequent light emission process can be repeated
again and again, and the material does not suffer any ageing.
Crystal:
Mineral glass with special anti-scratching coating.
Sapphire crystal transparent material made of crystalizing aluminium oxide
at very hot temperatures. Chemically synthetic sapphire is the same
as the natural sapphire used in jewelry, but without the coloring
agents that give the gemstone its various hues. Sapphire ( wether
natural or synthetic) is one of the hardest substance on earth. It
measures 9 on the Moss scale, which ia a system for rating the
relative hardness of various materials.
Water Resistant
Water resistance depends on several factors , some of which can be
affected by wear or simply by time. Gaskets can become corroded or
misshapen, cases denied or crystals loose or broken and needs
preventive maintenance. Some chemicals can corrode the gaskets and
make it vulnerable. Heavily chlorinated water can cause problems, as
can spray-on perfumes and hairsprays that work their way into the
watch's seams and damage the gaskets
The
different levels of water resistance as expressed in meters are only
theoretical. They refer to the depth at which a watch will keep out
water if both watch and the water are perfectly motionless..
In real life, the movement of the wearer's arm through the water
increases the pressure on the watch dramatically; so it can't be
worn to the depths indicated by lab testing machines.
Watches with the lowest level of water resistant are labeled simply
"water protected". They can withstand splashes of water but should
not be sumerged. Above that, the most common designations for water
resistant are regulated in the ISO 2281 water resistant and ISO 6425
