Precision and chronometry have been the sacred goals of horology since its start. For millennia, watchmakers and researchers have endeavored to improve the precision of mechanical devices, from the first sundials and monster checks in middle age holy places to the marine chronometers critical for route in the seventeenth and eighteenth hundreds of years and wristwatches that once filled in as clinical and logical tools.
In the nineteenth, 20th, and twenty-first hundreds of years, master establishments were founded to test and affirm the nature of the wristwatch’s precision.
The generally significant and popular one today is Switzerland’s C.O.S.C. (Contrôle Officiel Suisse des Chronomètres ), settled in La Chaux-de-Fonds.
Based on the ISO 3159 standard, this testing office has confirmed billions of Swiss watch developments since its commencement in 1973. Rolex is by a long shot the establishment’s greatest client, presenting the biggest quantities of mechanical developments for affirmation, trailed by Omega, Breitling, TAG Heuer, and Panerai.
Interestingly, the large numbers of chronometer endorsements gave every year account for just three percent of Switzerland’s yearly watch production.
There is another chronometer-testing office situated in Glashütte, Germany. Started by German gem specialist and watch maker Wempe, here the whole encased watch (not just the development similarly as with the C.O.S.C.) is tried in the best in class research centers introduced the antiquated Glashütte observatory. The tests are conducted as per the DIN 8319 norm under the support of the state workplaces for loads and estimations of Thuringia (LMET) and Saxony (SLME).
Apart from the chronometer-testing organizations, there are a modest bunch of different offices including Chronofiable (which structures part of the Qualité Fleurier ); its primary occupation is to test the dependability of sequentially created watches in exacting and thorough strategies, for example, stun and water obstruction and powers applied on components like the winding stem or pushers. To meet all requirements for the Chronofiable test, the watch development must have first procured a C.O.S.C. certificate.
Why, at that point, did Omega feel the requirement for another certification?
With numerous quality seals and chronometry authentications in presence, one may feel that in modern occasions there is no requirement for one more testing technique or hallmark.
While that might be valid, a portion of the present most renowned watch marks actually need to feature the nature of their watches’ mechanical greatness and fine workmanship with their own personal declarations; the Patek Philippe Seal, presented in 2009, is an extraordinary example.
Although that brand’s profoundly sought-after watches have been stepped with the best and oldest quality trademark in haute horlogerie, the Geneva Seal , which is only for watches delivered inside the canton of Geneva, Patek Philippe clearly wanted to separate itself by making another seal that goes even past those severe requirements.
One reason was that the Geneva Seal just applies to the development’s completing quality and doesn’t include precision.
For Omega, a maker drawing on a long custom of exactness timekeeping – even at the beginning line of games – precision is massively significant. The company’s name alludes to its first watch development made in 1894, the 19-ligne “Omega” caliber.
Famed for its exactness and vigor, the Omega development commenced an example of overcoming adversity that, when the new century rolled over, included numerous observatory competition awards for precision. Also, in 1932 Omega procured itself the most noteworthy conceivable task for a watchmaker: that of becoming the authority watch of the Olympic Games.
In later occasions, Omega’s co-axial escapement, initially developed by the shrewd independent watchmaker George Daniels , was designed to again increase current standards for exactness. This new innovation, which limits erosion and broadens overhauling periods, was the first new sequentially created escapement over the most recent 250 years. It has now supplanted the standard Swiss switch escapement in Omega’s movements.
The subsequent stage was the presentation of the non-ferrous Si-14 silicon balance spring in these developments. On account of the non-attractive properties of the material, the presentation of this pivotal component, multiple times better than a human hair, is unaffected by contact with attractive fields.
The utilization of silicon yet to be determined is an immense accomplishment as far as non-attractive innovation, a significant field in modern horological research as attraction is surrounding us in regular daily existence – from cell phones to hardware and family appliances.
So Omega took this significantly further and developed another norm in collaboration with Switzerland’s true expert for estimations, the Swiss Federal Institute of Metrology (METAS): the Master Chronometer authentication demands an uncommonly undeniable degree of attractive opposition of 15,000 Gauss in addition to an exactness pace of under 0/+5 seconds for each day.
Extensive testing for 10 days: the progression by-steps of Omega’s METAS Master Chronometer certification
For a watch to acquire the Master Chronometer confirmation, it first must have procured a C.O.S.C. authentication. At that point it will undergo eight tests executed over a time of ten days. These are completed in Omega’s spic and span processing plant, which is essential for the company’s settle complex in Biel.
The labs likewise house an office for METAS representatives, who test tests and screen the testing exercises and processes.
The exact testing steps are as follows:
1. Testing capacity of the C.O.S.C.- confirmed development during openness to an attractive field of 15,000 gauss.
This test inspects the watch’s development, putting it in two distinct positions and exposing it to an attractive field of 15,000 gauss. The legitimate working of the development is perceptibly checked utilizing a microphone.
2. Testing the usefulness of the watch during the openness to an attractive field of 15,000 gauss.
This test is like the first one, however here the whole watch is exposed to an attractive field of 15,000 gauss (and not simply the development). While presented to this attractive field, the working of the watch is additionally perceptibly checked utilizing a microphone.
3. Deviation of day by day chronometric exactness after openness to 15,000 gauss.
In this progression, the watch is exposed to an attractive field of 15,000 gauss; after 24 hours its chronometric accuracy is determined. The following day the watch is demagnetized, and the rate is determined after an additional 24-hour time frame. The deviation between the two days is recorded.
4. Normal every day chronometric pace of the watch.
This test is done more than four days. During this time, the watch is put in six unique positions and two substituting temperatures. It is again presented to an attractive field of 15,000 gauss. The chronometric accuracy is recorded every day. Toward the finish of the four days, the outcomes are utilized to ascertain a day by day normal rate.
5. Force reserve.
This test checks the force save of the watch by demonstrating that it continues to work at the constraint of its normal capacity.
6. Deviation of chronometric exactness in six positions.
In this test, the watch is put in six unique positions and its rate is recorded in every one. Out of these six outcomes, the deviation between the two most extraordinary outcomes (known as the delta) is shown.
7. Deviation of rate between power stores of 100% and 33 percent.
Here, the watch is put in six distinct positions and its rate is recorded at 100% force save in every one. This cycle is rehashed when the force save of the watch arrives at 33%. Omega at that point takes the normal aftereffects of the six measures during the two conditions of the force hold and provides the rate deviation between the two.
8. Water resistance.
This test lowers the watch, bit by bit applying more strain to the point of the expressed water protection from a limit of 150 bar.
Double affirmation and sharing results
In conclusion, the predicate “Master Chronometer” on the dial implies that the watch not just has procured two declarations – the METAS and the C.O.S.C. endorsements – yet additionally guarantees a completely straightforward testing process.
Customers can see the aftereffects of the extreme tests their watches have completed online by entering the declaration number on the red Master Chronometer Certificate card that comes with the acquisition of the watch.
Gold and dim at its best: Omega De Ville Trésor 40 mm in Sedna gold
One of the most as of late delivered Master Chronometers introduced in 2019 is another setup of the De Ville Trésor 40 mm, the brand’s wonderful physically twisted and outstandingly slim dress watch, which first made its debut in 1949.
What would i be able to say? Throughout the span of 70 years, this current watch’s appeal has stayed unaltered by time; it is an all around flawless illustration of effective vintage design in the best feeling of the word timeless.
Three variations were presented in 2019, one more pleasant than the other, and I immediately succumbed to the form that combines Omega’s Sedna gold case with a dark dial – in spite of the fact that I would wouldn’t fret wearing the steel model with a designed blue dial, either.
In 2019, the collection welcomes its first stove terminated finish dials that take into account especially expressive and enduring color. What’s more, by enduring I mean centuries.
I have consistently had a propensity for dull dim dials, and the color decision is perfect against the warm tone of Omega’s Sedna gold case. The Sedna gold cleaned hands and domed indexes richly contrast against the dim backdrop.
While the design addresses days of old’s style in the most ideal manner conceivable, the De Ville Trésor 40 mm flaunts a first rate modern development: Master Chronometer co-axial Caliber 8928 with manual winding contribution a solid 72-hour power reserve.
The De Ville Trésor 40 mm likewise flaunts brilliant completing – one model being the Sedna gold offset connect with outspread guilloche decoration that coordinates the eye directly into the core of the watch.
