THE HISTORY OF TRADEMARK

http://www.certina.com/history

Certina watches are known for their precision, reliability and sporty character. The sport watch brand has an international reputation built on quality Swiss workmanship, throughout its 125-year history.

1888. The sport watch brand is born

The brothers Adolf and Alfred Kurth set up their own watch production facility in the Swiss town of Grenchen. In this idyllic spot at the foot of the Jura mountains between Solothurn and Biel, the brothers and their three employees work in an annex to the family home. Within a short time business is flourishing, and so in the following years various extensions are opened and new employees taken on.

1906. A new brand name

In 1906 the Kurth brothers introduce a brand name for their watches: "Grana", short for "Granacus", the Latin name of Grenchen. The quality of this timepiece is immediately recognised and earns several awards. In the 1920s Alfred Kurth’s sons Erwin and Hans join the company and see it through the difficult time of the Great Depression.

1939. Certina. With Security

During the 1930s the company increasingly uses the brand name Certina, for a good reason: it is easy to pronounce in all languages and is based on the Latin word "certus", which means "sure". The brand is officially registered in 1939 and in 1949 is chosen to be the sole brand name.

1959. The DS Concept is born

In 1959, the company brings out the first Certina watch with DS Concept. The Certina DS is an extremely shock-resistant automatic watch with water resistance up to 20 bar (200 meters). This sets new standards for a whole generation of wristwatches.

1960. Expedition to the Himalayas

The Certina DS accompanies an international expedition on the first successful ascent of the 8,167-metre-high Dhaulagiri in western Nepal. It overcomes all the challenges – from strong temperature fluctuations to considerable height and pressure differences – with no problem at all.

1965. With Sealab II at the bottom of the ocean

The Certina DS takes part in the US Navy's Sealab II underwater project, which involves scientists and divers working in a diving station in different areas of marine research. They confirm that the Certina DS is absolutely reliable under all conditions.

1969. A successful dive

The innovative DS-2 Super PH 500 M is part of the Tektite underwater experiment, in which four scientists live in two underwater residential tanks for two months under NASA observation. The Certina models worn by the scientists achieve the very best scores.

1970. Flying high

A Japanese expedition to Mount Everest is accompanied by Certina watches, which also stand up to these highly challenging conditions. During the expedition, the Japanese skier Miura achieves one of the most daring ski runs of all time, descending through 1,000 metres from an altitude of 8,000 metres, while wearing a DS-2 Chronolympic.

1971. Time to listen to one's body

The Certina Biostar is the first watch in the world to display a person's daily biorhythms. At a glance it shows the wearer's physical, mental and emotional biorhythms.

1973. Champions together

The Belgian rider Roger de Coster wins the motocross world championships 500cc class for the third time, proudly wearing his Certina DS 288.

1976. A powerful duo

The ultra-robust and scratch-resistant DS DiaMaster attracts attention everywhere – including on the wrist of the famous American heavyweight boxer Muhammad Ali.

1983. A new chapter in the history of watchmaking

Certina joins the newly founded SMH Group, which is led by the visionary entrepreneur and watch-lover Nicolas G. Hayek. SMH becomes the world’s leading watch group, and is renamed the Swatch Group Ltd. in 1999. Certina sport watches are in the middle-price segment of the corporate group's range.

1995. Clearly a sport watch

With its new Cascadeur models, the Certina brand's skill in making sport watches can be seen at very first glance: the strap of this timepiece is designed like the chain of a motorbike, and two eye-catching metal rods over the sapphire crystal provide extra protection.

2002. Off-road timekeeping

Certina continues to extend its involvement in motorsport, and can now be seen on the wrist of the popular rallying world champion Colin McRae.

2004. Absolute precision

The DS-3 1000m recaptures the heritage of Certina’s famous diver's watches. This automatic timepiece is water resistant to a record-breaking depth of 1,000 metres.

2005. On the winners’ podium

As the official sponsor of the Sauber Petronas team, Certina celebrates its debut in Formula 1, a discipline to which it will remain loyal for many years. At the same time, the brand is delighted at the 125cc class world title win by motorcyclist Thomas Lüthi, whom it has sponsored since the beginning of his career. These sporting successes are reflected in the launch of the DS Podium, whose sporty design and precision make it one of the most popular and successful Certina watch families to this day.

2011. An exceptional athlete

The Norwegian Ole Einar Bjørndalen, most successful biathlete in sporting history, joins the international Certina family as an official brand ambassador.

2013. 125 years of Certina

On the occasion of its 125th anniversary, Certina presents not only a completely new and fresh corporate identity, but also three new watch movements. The Powermatic 80, a highly precise movement with a power reserve of up to 80 hours, the C01.211, an extremely reliable chronograph and the ultra-accurate Precidrive™ movement, the latter representing a new generation of quartz watches whose precision is comparable with that of chronometers.

2015. New partners in speed

Certina is expanding its presence in motor rallying, as the official partner of the Abu Dhabi Total World Rally Team, one of the most famous and most successful teams in this sport. It is also entering into partnership with the renowned ADAC GT Masters. As the official timekeeper in one of the most exciting racing series in Europe, the brand is consolidating its reputation as an authentic sport watch, which is at home at the world's major motorsports events.

RECOMMENDATIONS

All Antique watches are mechanical. Many repairs will not be cheap, as most likely they will require replacement of non-standard parts (unlike most late model watches).

  • Antique watches should not be beaten or dropped - because repairs may be expensive.
  • Antique watches are generally NOT waterproof. This is because waterproofing was not in general production until the middle of the 20th century for most watches. Therefore you should protect your antique watch from exposure to moisture.
  • If your watch becomes wet it should be dried off quickly. Carefully open all covers and use a hair drier to blow dry the movement, dial, covers, crown. This will reduce the amount of rust.
  • If your watch becomes wet with any kind of salt water you should immediately immerse or spray your watch with fresh (no-salt) water to remove all the salt from the works before drying the watch completely. Any salt left in the watch will combine with moisture in the air to rust metal components of the movement, case etc.
  • Winding any mechanical watch tight may break the mainspring. If you can avoid it do not wind the watch hard.
  • When adjusting the hands of your watch, move them in a clockwise direction only. Counter-clockwise adjustments may damage the movement. It is desirable to adjust the hands of your watch at the same time every day. An automatic or self-winding watch should be worn for at least 8 hours a day. It is a mechanical watch in which the mainspring is wound automatically as a result of natural motion of the wearer's arm, to provide energy to run the watch, making manual winding unnecessary.
  • If you must adjust counter-clockwise make it for small adjustments only (i.e. for minutes, NOT hours).
  • Be careful and gentle when adjusting the movement speed (faster or slower). Don't make sharp movements, and don't touch other components in the movement especially the pendulum mechanism.
  • Every 2-3 years it is necessary to service and oil vintage watches. If the course of your watches is worsening and the accuracy of the reduction in the duration of the clock (autonomy) from one fully wound spring - it need a service.
  • IF the watch is dirty - allow the watch to run down, don't wind it again until you have it serviced by a qualified watch repair expert. Dust will absorb and remove important lubricants and cause the movement pieces to wear down.
  • To clean the case, dial and crystal you should use a cloth that does NOT leave fibers as these may get caught up in the movement. Check with your Watch repair expert to get an appropriate cloth.
  • Keep your antiques watch away from magnets. Strong magnetic fields may affect the accuracy of your watch since some vintage watches were made with iron based components in the movement.
  • Most Cases and Covers are fine components and will not handle abuse well. The watch should not be shaken, beaten, or stressed.
  • Antique watches generally experience an error of up to 5-7 minutes a day. Any accuracy of +- 5 minutes is very good.
  • Mechanical watch is not recommended to use for engage in extreme sports, and expose them to excessive vibration loads. Recoil force, which take on the clock, affect their reliability and precision. No matter how perfect was not anti-shock mechanism, there is always the chance of excessive load that details of the mechanism can not survive.
  • Watch with calendar. It is not recommended to adjust, the date between 20.00 and 06.00, because at this time involved a mechanism for automatic adjustment date. Translation pointers calendars manually in this position arrows may damage the mechanism. Date changes should be made, relegating pre-clockwise to lower sector of the dial (for example, to position 6 (18.00) hours).
  • Chronograph watches. In most cases, these watches contain the "start/stop" button and "reset" button. It is strongly recommended not to press the "reset" if the chronograph is running. Before you use the "Reset" button need to stop the chronograph by button "start/stop". Using the "reset" when running chronograph can damage the mechanism of most models of watches.
