Ventura v-matic Chronometer
Technically and by design, v-matic chronometers are widely
recognized as important developments within the Swiss watch
industry.
To meet the demanding standards of the COSC, each part
of the select automatic movements is rigorously tested and
carefully polished prior to assembly by master watchmakers.
In the process called «tuning», a movement is often stripped
down and assembled again several times, until it reaches the
benchmark set forth for each and every v-matic chronometer.
Case and bracelets are made of instruments steel with a low
nickel-content, of highly scratch-resistant Titanox
®
Durinox , both materials being exclusive to Ventura. Titanox
is a patented process of hardening pure-grade titanium.
The Durinox processing hardens stainless steel in a similar
way. The construction of the v-matic case is dedicated to the
protection of the precious movements against humidity.
As Titanox and Durinox are not suitable for screw-type fix-
tures, a new technique was developed to press the caseback
with a weight of more than 80 kg. onto all v-matic cases to
reliably safequard water resistance. Likewise, the sealing of
the crown and stem, - the only externally exposed move-
ment parts- is a high-tech construction. The v-matic sports
models feature crowns, which are screwed onto the case
for additional safety, allowing you to wear your watch when
swimming or diving.
Above all, it is Hannes Wettstein's outstanding architecture
that gives the v-matic its unique character.
Freed of all fashion ornaments, the clear, functional form is
simultanously both classic and futuristic.
The prominent German watch magazine CHRONOS described
it as follows: «the v-matic appears like a guest from the future
and will always remain years ahead of other watches.»
Important information
Power reserve
Fully wound, your v-matic has a power reserve of about 40 h.
The winding of the automatic mechanism depends on the
intensity of your movements to activate .
Hand-winding
Before wearing the watch for the first time or after it was not
in use for a while, an Automatic watch should be manually
wound with the crown.
Setting the date
A little trick ensures, that the date-indicator correctly jumps
at midnight (and not at 12h noon) to the next day: Set the
date first to the previous day; then forward the hands until
the date jumps. Now you know that the hands are positioned
at midnight and you can set the hands to the correct (a.m.
or p.m.) time.
Screw-on crown
Adjustments of time and date are possible only after the
crown is detached by turning it counterclockwise; it is essen-
tial that it is thereafter tightly screwed back (clockwise) onto
® or of
the case.
Be careful not to damage the threading: Do not use force
when encountering resistance; loosen the crown again and
lightly press it against the case while screwing it in.
(Damaged screwtaps and water-damages because of non-
observance of these important instructions will void the
warranty.)

Water resistance
All v-matic models have a water resistant construction and
are individually tested. We nevertheless do recommend you
to take off your valuable chronometer before swimming and
diving, because even slight shocks applied to the crown or
rapid temperature changes can damage the sealings and
impair the water resistance.
Only models featuring screwed-on crowns are suitable for
wear in water but we recommend a periodical water resist-
ance- and reliability test every 24 months or prior to extended
water activities. Fogging of crystals may not necessarily indi-
cate the entry of humidity, it can also be caused by shock-like
temperature changes. A check-up by a specialist is highly
recommended upon appearance of fogging.
Luminous hands and dial-indices
These enable you to read the time on various v-matic models
in the dark. Today, Ventura exclusively uses environment-
friendly «Superluminova» luminous paint, which starts glowing
immediately in darkness. (On earlier watches still on the mar-
ket, luminosity is obtained from a tritium patty, which requires
at least 5 minutes of total darkness to become active.)
