Three-dimensional Tourbillon Makes The Bi-wing System More Divided Jaeger-lecoultre Duomètre Dual-axis Tourbillon

At first, when you saw the tourbillon structure of Duomètre à Sphérotourbillon, it is inevitable to think of Jaeger-LeCoultre Gyrotourbillon 1 spherical tourbillon released in 2004, and a spherical aluminum alloy frame with a solid tourbillon outer 60 One second rotation, one second frame at an angle of 90 ° to the outer ring, one second rotation in 24 seconds; ”08 Tourbillon No. 2 was mounted on the square Reverso series, and a cylindrical spring was used to improve isochronism The rotation period of the frame was also accelerated to 18.75 seconds, and it was arguably the fastest tourbillon in the world at the time of publication.

The 9 o’clock tourbillon is tilted at 20 ° with two axes, the outer titanium frame rotates for 30 seconds, the inner escapement rotates for 15 seconds, and a cylindrical hairspring is used to improve the stability of the balance wheel.

Feature one: cylindrical hairspring helps to improve travel time accuracy
This Duomètre à Sphérotourbillon uses the technology and concept of making ultra-complex tourbillon in the past. Its dual-axis tourbillon at 9 o’clock is inclined at 20 ° on both axes, and the three-dimensional titanium metal frame on the outer ring rotates once every 30 seconds. The internal escapement system runs at a speed of one revolution every 15 seconds at the same time, and the speed is much faster than the general tourbillon, and the visual dynamics are more flexible. In addition, a cylindrical hairspring is used. The end curves of the head and tail of the hairspring can cause the hairspring to vibrate in a concentric circle. Due to the large volume of the cylindrical hairspring, it was mostly used for boat clocks or pocket watches, but its isochronism is better Generally flat hairsprings and even Breguet hairsprings were transplanted to watches to test the production technology.

The eccentric dial at 3 o’clock can read the local hour, minute and date information, and the small dial at 12 o’clock shows the second time, which is relatively practical.

Feature two: more accurate than the general tourbillon
The highlights of the Duomètre series include the dual power system. The Cal. 382 is equipped with two barrels. One is designed to provide escapement power and the other is to provide all indication functions. The box is wound. Thanks to the dual-wing system, Duomètre à Sphérotourbillon has the function of resetting the second hand at 6 o’clock, and it can be reset to zero by pressing the pusher at 2 o’clock, but the escapement system will continue to operate, so the tourbillon still It will continue to rotate, to avoid the slight error that may occur before the balance wheel is stopped and restarted before returning to the original normal vibration frequency.

Two barrels on the left and right of Cal. 382. The central ratchet is engraved with gold lettering to indicate the power. The plywood is decorated with the classic sunburst sanding of the Jaeger-LeCoultre movement.

Feature 3: There are two places to watch
Duomètre à Sphérotourbillon dual-axis tourbillon dual-power supply Although it is no longer as clear as the first series in the general travel time and complex timing power is so clear barriers, but the dial design also roughly continues the relative concept of the two wings, the dial at 3 o’clock includes Hours, minutes, and dates are displayed. Compared to the dual-axis flying tourbillon at 9 o’clock, about 12 o’clock is second place time, 6 o’clock is small seconds, and the mobile display is moved to the 1, 4 o’clock position.

Iwc Engineers Chasing Chronograph Titanium Watch

Schaffhausen-A masterpiece of precision engineering technology is grandly available. This is the new engineer’s chase chronograph titanium watch from IWC. In addition to the sophisticated technology contained in its chronograph, this masculine timepiece is also one of the most rugged IWC watches. This watch is made to the highest quality standards, and it means a dream come true for every man who seeks a fulfilling life.
    Engineering is to solve difficult technical problems with clever ideas. It is a delicate art. This new engineer’s chronograph titanium watch carefully crafted by IWC watch experts in Schaffhausen is the masterpiece of this fine art. In terms of design and function, it is in the same vein as this legendary watch series from 1954 to 1955.
Dreams come true with titanium
    The new engineer’s chase chronograph titanium watch from Schaffhausen IWC is equipped with a solid and reliable caliber 79230 and a 45mm titanium case, which has a stunning appearance. With the introduction of this watch, the engineer series is equipped with the chronograph function for the first time ever. In addition to superb technology, this new piece is equally striking in appearance. In addition, the satin finish of the ‘first’ titanium case makes the surface appear silky shiny. The appearance of this watch has many features, including five screws with diamond-like carbon coating (DLC) on the bezel. The screw head blends perfectly with the black rubber-coated buttons and crown shoulders. The vulcanization effect of rubber perfectly highlights the watch’s heavy appearance and smooth control. The redesigned dial looks clear, pleasing and clear. To distinguish the displays more clearly, the designers used blue for the first time to create a color palette that complements this timepiece. The hour, minute and small seconds (with stop) dials are recessed, while the luminous materials embedded in the rhodium-plated hands are black. At night, this function of the watch begins to play its important role. Considering the weight of the watch and its 16 mm case thickness, the designer deliberately omitted the soft iron inner case. The convex case ring design highlights the distinctive ergonomic concept, combined with a total weight of only 130 grams, making it exceptionally comfortable when wearing the watch. Engineered chronograph titanium watch with proven water resistance up to 12 bar, tough engineer rubber strap, double-sided anti-reflective sapphire glass, screw-in case back and crown, enough to withstand Extreme conditions.
    The chase time function is an extension of the timing device technology. With this function, two different time periods can be measured in one minute. To put it simply, just press the button to start the chronograph function, and the two center chronograph seconds hands will start running. Since the two hands completely overlap, the second chronograph hand cannot be seen immediately. At this time, the wearer can choose to repeat the measurement time within one minute. When the timekeeping function is activated, press the third button at the ’10 o’clock’ position, the upper chronograph hands will stop, and the lower chronograph hands will continue to operate until the normal It will stop after the start / stop button. Using this method, two different short periods can be measured. If you press the tracing hand button again, no matter the chronograph hand is running or stationary, the tracing hand will immediately return to the top of the chronograph hand. This function can only be achieved through continuous sublimation based on rich experience in watchmaking.
Titanium-a glamorous material
    At IWC, innovation is a long tradition: As early as 1980, IWC had taken the lead in using this advanced material, and its titanium chronograph watch led the industry first. Now, IWC has accumulated rich experience in handling this lightweight, almost never wearable and extremely skin-friendly material. By the end of the 1970s, however, with the assistance of aviation experts, Swiss watch maker IWC had mastered the necessary know-how to process and heat treat titanium. Titanium is 43% lighter than stainless steel, but it has excellent overall corrosion resistance, extremely low thermal conductivity and electrical conductivity. Titanium is one of the most unique and expensive materials in the world. Its unique color and lustre can enhance the appearance and masculinity of the engineer’s chronograph titanium watch. It is a veritable ‘engineer’ both in function and appearance.

Christie’s Will Auction ‘hai Selassie Patek Philippe Black Ref. 2497 Black Plate Watch’ Again

Time back to November 9, 2015, at the Geneva auction held by Christie’s, a Patek Philippe Ref. 2497 black gold-plated dial watch has attracted widespread attention in the collectors. This is the Ref. 2497 watch with a black gold-plated dial, making its debut in the auction market, with an estimated value of 500,000 to 1 million Swiss francs. The watch was originally owned by Ethiopian Emperor Haile Selassie, who later gave the watch to a friend.

Haile Selassie Ref. 2497, a rare Patek Philippe watch, will be auctioned at Christie’s this May

   The auction was originally scheduled, but due to disputes over ownership, the watch was withdrawn at the last minute of the auction on November 9, 2015. On May 15 this year, the Patek Philippe Ref. 2497 watch, once owned by the Ethiopian Emperor Haile Selassie, will return to Christie’s Geneva auction. The ownership dispute has been resolved after confirmation.

Ref. 2497 on the back of the watch is engraved with the name of Emperor Haile Selassie

   So, back to this watch, why is it so special? Ref. 2497 succeeds Ref. 1526 and is one of the early perpetual calendar models produced by Patek Philippe. The production cycle of Ref. 2497 is from 1950 to 1963. It is equipped with a Caliber 27-SCQ manual winding movement, a thick case and a stepped bezel design. The Ref. 2497 watch participating in the auction is particularly special, most notably with a black gold-plated dial, which is very rare in Patek Philippe antique timepieces. In addition, the combination of gold-plated printed time stamps and Arabic numerals is also quite unusual and has rarely appeared in auctions before.
   So where does this watch come from? In fact, it was given to Haier Selassie by Italian entrepreneur and pilot Federico Bazzi in 1954. Then, Haile Selassie gave it to ‘a well-known figure in Africa’, who passed the watch to future generations, and finally commissioned Christie’s auction. As we know, tracing the origin of a watch is not easy, so this type of information can be very helpful for auction sales. All in all, I am very glad to see this Ref. 2497 watch return to the auction, after all, it was deeply regrettable that it was abandoned halfway through.
