The mysterious black dial with striking white markings adds a sense of fashion to this uninhibited sports watch. Its characteristic matte black rubber surface is made through a complex vulcanization process, bringing a new visual and tactile experience to a 44 mm diameter stainless steel case. Each stainless steel case is pressurized and heated in a special mold, permanently fused with this warm-touch, anti-slip rubber material. The strap is also made of the same kind of black rubber, and it is connected to the case by the new bracelet quick-change system of the marine timepiece series.
    Equipped with a newly developed rotating diving bezel with a minute scale that can only be adjusted counterclockwise. Compared with the rotating inner ring adjusted by the crown, the non-slip bezel has two advantages: it can be easily operated with gloves before entering the water. It also highlights the brightness of this important diving device (along with the minute hand). The scale of the bezel is covered with 4 mm wide sapphire crystal glass, which is firmly embedded in the surface of the bezel. The bottom of the sapphire glass ring is coated with a thick Super-LumiNova luminous coating, which can shine through the surface of the sapphire glass ring or the digital scale even without lighting.
    The innovative quick-change system of the bracelet, just loosen the mechanical locking device on the bracelet by hand, you can remove and replace the bracelet or strap without tools, and the ‘fast’ replacement process only takes a few seconds. The rubber strap can also be replaced with a clasp-type extension strap to allow the watch to be worn outside a wetsuit. The marine timepiece ‘Galapagos Islands’ has a pressure-resistant function that can withstand a pressure of 12 bar, which is technically comparable to its predecessor, the marine timepiece automatic chronograph, with a power reserve of 44 hours when fully wound, and Can accumulate recording time up to 12 hours. The dial’s numerals and rotating bezel are still a strong contrast between black and white. Only the small second hand is yellow, which serves as a pointer for checking functions.

[Comment]
    If there is a brand in the world who is dedicated to modifying the ETA movement and can do it to the extreme, it must be Athens. This brand can be modified from simple three-pin to complex perpetual calendar by modifying the ETA movement. And the dial of Athens is very fancy, and its unique large-scale hollow hands are also one of the brand marks. Because it is a dual time zone display, a small dial is used to realize the time display in the second time zone of 24 hours. In addition, the Sonata Dual Time in Athens also provides alarm services. This is also a small complication. At the same time, we can see the strength of Athens to modify the ETA. Basically it can be regarded as half a self-produced movement. The valuation given by the auction house is also in place, and the transaction price is just above the maximum ceiling of 25,000 US dollars. However, it is difficult to say whether such prices have room for appreciation. Gold watches have always been an element of high-end products in the watch industry. After all, making watches with precious metal materials is an important indicator for each brand to position its product line. Any complicated watch will be represented by precious metals. Someone once joked that the ‘starter’ mentality of gold watches only prevails in the Mainland. In fact, otherwise, gold watches still have works close to art, and they can be accepted worldwide.

Coinciding with the tenth anniversary of Lange’s first mechanical watch with a precision jump display, the brand has launched a new work featuring a new homemade movement and built-in superior extra features. ZEITWERKDATE’s glass date ring displays the current date in red.

 With the launch of ZEITWERK in 2009, Lange wrote a new chapter in timing. As the first mechanical watch with a constant-force escapement and precise hour and minute display, it has won awards for this innovative concept and eye-catching appearance. The unique device advances the digital disk in one second, and even pushes all three disks at the same time as you step into the next hour. ZEITWERK cleverly controls the power that needs to be released, which can be described as a real ‘time machine’.

 Ten years later, Lange’s digital mechanical watch is ushered in a new design movement with additional functions-a ring-shaped date display around the entire dial, harmoniously integrated with the ZEITWERK design. ZEITWERKDATE is equipped with a 18K white gold case with a diameter of 44.2 mm, a gray dial and a red date.

 The circular date ring is made of glass with numbers 1 to 31 and the current date is indicated in red. To show this effect, the small color segment below the date ring will go further before midnight; after a month, it will make a full circle on the dial. This layout makes the date display moments clear and easy to read at a glance. In addition, the corrector at 8 o’clock can adjust the date display; switching power will be generated when released.

 For Lange’s R & D personnel, ZEITWERK is both a challenge and an opportunity. Limited by the large digital dial and the attention dial with time bridge, it is difficult to add a traditional date display, let alone a large calendar display. Therefore, researchers need a completely new design solution. The concept of the instant jump date ring is unique and also matches the ZEITWERK design.

 Another big innovation of ZEITWERKDATE is the extra button at 4 o’clock. This can be used to advance the hour display separately, thereby solving the problem caused by the date display itself. Since the time setting must be accurate 24 hours, the minute-by-minute adjustment through the crown is a very time-consuming process, and the configuration of the hour button is also Bring a lot of design changes. Each time the button is pressed, the clutch separates the hour ring and the word-jumping device, allowing independent calibration outside the movement switching cycle. Release the button to generate switching power.

 The new L043.8 manual winding movement stands out with its well-organized movement structure. The patented constant-power escapement is responsible for two tasks: this constant-motion device provides uniform power to the balance wheel throughout the operating period. The unit will also provide power once a minute for switching the three-disk skip display.

 The 512-piece movement is adorned with fine decoration and becomes the unique Lange logo of ZEITWERKDATE. Through the sapphire crystal glass back cover, you can see some components, such as the sculpted ratchet and the delicate perpetual bridge.
