When The Chronometer Standard Isn’t Good Enough (Anymore)

When The Chronometer Standard Isn’t Good Enough (Anymore)

For some dhgate watches marks, the chronometer accreditation is simply not sufficient anymore.  The world has changed since 1973, when the Contrôle Officiel Suisse des Chronomètres, the Official Swiss Chronometer Testing Institute, was founded.

Lebois & Co is pleased to introduce to you their new dhgate watches the Venturist. Other than an attractive dhgate watches (I will come to that later), this dhgate watches has more to it. It has been tried by Timelab and gotten an Observatoire Chronométrique+ certification.  To comprehend what this is, we need to recap the standard chronometer certification.


With a chronometer (not chronograph) ensured dhgate watches you can trust your dhgate watches is precise. To be more explicit, it has a normal day by day rate between – 4 seconds and +6 seconds. For a mechanical dhgate watches that’s quite slick to have. In request to have a chronometer dhgate watches or chronometer ensured dhgate watches to be exact, its development – or dhgate watches – probably been shipped off the authority Swiss Chronometer Testing Institute for some arrangement of tests. These tests are defined by the COSC and dhgate watches brands want to sit quiet about these, they simply need to send the developments with a ‘test’ dial and ‘test’ crown. Inevitably, they will get the developments back. The individuals who didn’t breeze through the assessment should be changed again, the individuals who finished the assessment will be cased. The developments with confirmation can have the word ‘chronometer’ on the dial. That’s right, it is an ensured name to use on a dial.

The current chronometer certificate depends on the ISO 3159 norm. This standard was defined (“Lays down the definition of the term “chronometer”, describing the classifications, the test program and the acceptable minimum necessities for wrist-chronometers.”) in 1976 and changed again in 2009. Right up ’til today, this is the structure that the COSC uses to confirm wrist watches.

Watch developments are tried for 15 days in the research facility of COSC, on two unique factors, namely:

  • temperature (8 °C, 23 °C and 38 °C).
  • the position of the dhgate watches (3 o’clock, 6 o’clock, 9 o’clock, dial on top, dial on the bottom)

A complete rundown of the testing method can be found on the authority COSC site .

So, what’s the point of messing with an Observatoire Chronométrique+ affirmation? Isn’t a chronometer evaluated Lebois & Co Venturist sufficiently not? All things considered, you presumably have seen that brands like Rolex, Omega and Grand Seiko for instance, begun to accept some stricter guidelines. Great Seiko utilizes a normal every day pace of – 3 and +5 seconds, Rolex guarantees – 2 and + 2 seconds and Omega utilizes just sure rates from 0 to +5 seconds. There are most likely some a greater number of brands that utilization stricter principles than COSC, however let’s adhere to these. Since what’s more, is that these developments are tried in the wake of casing. This implies that these tests give a preferred reenactment of day by day use over testing the developments only.

That still doesn’t answer the topic of why brands should trouble in having a more exacting test structure than COSC offers. Indeed, as you most likely are aware we live in a quickly changing world. We are encircled by (customer) gadgets the entire day, that bring attractive fields with them. Think of your iPad and defensive cover, or the security territory at an air terminal, or your worker park (at home or in your company). Attraction influences the pace of your dhgate watches definitely, one reason that certain brands use silicon hairsprings for instance. What COSC additionally doesn’t test, is the water opposition of a dhgate watches (as they mainly test uncased developments) and the force save of a movement.

Observatoire Chronométrique+ certification

Lebois & Co needs to have an effect in this field. Which began with a fantasy, and acknowledgment with the assistance of some crowdfunding, transformed into a genuine dhgate watches company today. To have an effect in the jam-packed universe of dhgate watches brands, originator Tom van Wijlick chose he expected to accomplish something unique. The nature of the Lebois & Co dhgate watches was at that point according to his own exclusive requirements ( as you can peruse here ), he needed to ensure that an independent research center would underline this.

Every Lebois & Co Venturist dhgate watches will be tried (and confirmed) by Timelab. Timelab is a Swiss foundation operating under the authority of the State of Geneva and its involvement with watchmaking lab traces all the way back to 1886. The famous research center has three exercises: the Poinçon de Genève (Geneva Seal) confirmation, the Observatoire Chronométrique+ accreditation and a horological lab. With their Observatoire Chronométrique+ standard, Timelab has introduced a stringent confirmation that is open for Swiss made dhgate watches The Venturist will be furnished with Timelab’s OC+ standard.

Chronometer and WR

The OC+ certificate depends on more exhaustive and comprehensive testing than the standard ISO 3159(:2009), which permits the dhgate watches to get the title of ‘chronometer’, utilized and followed by research centers like COSC. Instead of just verifying the chronometric execution of uncased developments, the OC+ methodology does as such ‘on-the-wrist’ for the completely gathered dhgate watches under different conditions.

The water opposition of the Lebois & Co Venturist is likewise tried by Timelab. To guarantee a dhgate watches is (100 meters) water safe according to the ISO 22810 standard each dhgate watches needs to withstand 3 distinct tests: an air overpressure test, a water overpressure test and its water obstruction into low profundity. For the last test, the Lebois & Co Venturist is set inside a water tank at a profundity of 10 cm for a fixed length of 60 min. At that point, to affirm water obstruction, another buildup test is applied and again no buildup ought to show up inside the dhgate watches to pass the test.

The attraction test is performed by applying an attractive field of 4800 A/m to the dhgate watches in 3 unique positions. Subsequent to applying the attractive field the precision is estimated to enlist the effect of the attractive field. At that point the dhgate watches is demagnetised and another estimation is performed. The two estimations need to fall within the rules indicated in the ISO 764 standard.

Last however not least, the Lebois & Co Venturist is tried on its accessible force save. A complete portrayal of all tests performed on the Venturist can be found , on the site of Timelab.

Every individual Venturist is tried in Geneva for 21 days and is just granted the ‘Observatoire Chronométrique+’ declaration if all tests are 100% successful.

Lebois & Co Venturist

Now, on to the dhgate watches It isn’t an oddity in that capacity, as it was at that point introduced to you last October ( here ). Regardless of the number of authentications are tossed at it, in the event that you don’t like the manner in which it looks, for instance, you’re not interested in any case. The beneficial thing is, that the Lebois & Co Venturist looks very pleasant. It would seem that a legitimate instrument dhgate watches maybe even a piece Explorer-ish, with its huge luminous numerals at 12, 3, 6 and 9. It is a profoundly clear apparatus dhgate watches with a 41mm measurement and little unnecessary things on the dial. Like a date window, for instance (yeey!).

The stainless steel (grade 316L) case is 10.5mm thick and has an excellent shape, including faceted hauls. The case band has a cleaned finish, while the highest point of the drags and bezel have a satin brush finish. The two sides of the case have a sapphire crystal.


As you can see, the dark dial of the Lebois & Co Venturist is entirely intelligible. The hour markers are loaded up with Super-LumiNova (BGW9 grade), just as the hands. This, for better intelligibility in low-light conditions. On the dial, you will likewise find the formally guaranteed chronometer indication as this actually remains part of the OC+ certificate. ‘Venturist’ is printed in red on the dial, giving it a fun loving touch. Similarly as the depression theme on the dial beneath the hour markers. You quickly notice that Lebois & Co put a ton of thought in the plan of this dial, including the length of the hands that arrive at every one of their scales. Sadly, this isn’t generally the situation with dhgate watches brands.


Inside the Lebois & Co Venturist we find the type LC-201 development. This self-winding development depends on a Sellita type and furnishes the dhgate watches with 38 hours of force hold. This type LC-201 development has Côtes de Genève and perlage beautification and blued screws. This can be respected through the sapphire case back. Winding and setting of the development are done through the rich looking Lebois & Co marked crown.

As you can see, the case back additionally has all the important information engraved in there. The brand & model name, reference number and the way that it has a chronometer testament. The case back is screw-in and as composed over, the dhgate watches is WR to 100 meters (~ 10 bar).

The Venturist comes with a dark cowhide cordovan tie and a (dark) NATO strap.

Pricing and Availability

The actuality that the Lebois & Co Venturist has been affirmed with a more exacting norm than initially arranged, is a major in addition to. As far as I might be concerned, it is likewise interesting to see that Lebois & Co isn’t just a task, however gradually becoming a brand. The Venturist may really be their entryway to build up this. With the determinations and looks of this dhgate watches there is nothing incorrectly, it consummately holds facing a portion of the more notable brands out there (and have been for decades).

Lebois & Co’s retail cost for the Venturist is €2500,- and temporarily, this comes with 25 offer testaments in the company (representing an estimation of €1000). These offers in Lebois & Co additionally permit you to buy dhgate watches later on with a 40% markdown on retail costs (substantial for a time of 4 years).
