The water resistance of your ROAMER watch is designated in ATM (atmospheres) on the back of its case. The specified ATM is equal to the tested atmospheric pressure. Water resistance is not a permanent and unchanging characteristic: it may be affected by ageing of gaskets, by accidental shock to the crown or abrupt fluctuations of temperature. We recommend that you have the water resistance of your watch checked once a year by an authorized ROAMER service center. Never activate the time-setting crown and/or the pushers while the watch is under water and make sure that the crown has been pushed/screwed down tightly after every operation.
For the manufacture of all accessible components of its steel watches, ROAMER has selected a very high quality and antiallergenic stainless steel from the 316L family. The advantages of this material are its high corrosion resistance and excellent durability. The same kind of steel is also used in surgical applications.
Leather is a high-quality, natural product. Irregularities in its colour and texture are inherent characteristics and a typical sign of quality that proves the genuineness of the leather. To guarantee its outstanding aesthetics, longevity and optimal comfort on the wrist, all ROAMER leather wristbands are fabricated from finest leather.
Leather is an organic substance that ages more rapidly under moist conditions, so it is advisable to avoid exposing your leather wristband to excessive moisture.
All ROAMER watches are made in Switzerland and bear the “SWISS MADE” quality label. The words “Swiss Made” printed on the dial are a seal of quality from the Swiss watchmaking industry. ROAMER’s watches stand for the finest-quality Swiss craftsmanship. They’re manufactured from first-class materials via ultramodern production methods and with the utmost meticulousness. All components undergo rigorous quality controls after each step in the fabrication process, and each completed watch is thoroughly tested as well: its aesthetics, the accuracy of its rate, its proper functioning and its water resistance are scrutinized while the timepiece is submerged in water and while it is subjected to air pressure and water pressure.
The manmade sapphire used for your watch’s crystal is extremely hard and scratch-resistant. With a grade of 9 on the Mohs scale, nothing but diamond (10 on the Mohs scale) is harder than sapphire. A watch glass fabricated from manmade sapphire has exactly the same crystalline structure as natural sapphire. It doesn’t become streaky and it’s extremely scratch resistant. With a very few accordingly identified exceptions, all ROAMER watches are equipped with sapphire crystals. The sapphire crystals that ROAMER uses are treated with an antireflective coating to guarantee optimal legibility.
Also known as IP Plating, is classed among the PVD processes and one of the most advanced surface coating procedures till date. Ion plating relies on a vacuum-based, plasma-assisted method to precipitate a thin layer of precious metal on to the base material. This process can be used to produce a range of exciting and aesthetically pleasing colors. Furthermore, the ennobled surface is very long lasting and highly resistant to corrosion. It protects the watch against wear and tear.
A balance is a precisely fabricated metal wheel that ceaselessly rotates back and forth. The ends of its staff serve as the pivots for its continual oscillations.
Together with mass of the balance wheel, the hairspring forms an oscillating system. The regularity of the balance’s oscillations (i.e. its isochronism) determines the accuracy of the timepiece’s rate.
Watchmakers define the frequency of the oscillations of the time-subdividing component in terms of the number of hourly beats or swings in each direction, i.e. in semi-oscillations per hour (So/H). With each semi-oscillation of the balance, the escape wheel advances by an increment of one tooth. The most common frequency is 28,800 So/h, i.e. four hertz.
