Glashütte’s geese neck fine-tuning innovation is the combination of fast and non-calorie, and the adjustment is divided into detailed steps to avoid the inevitable deviation of the fast needle. And although the needle is fine-tuning, through the design of the gooseneck device, adjust the speed is slow through the screw rotation, to facilitate a lot.
Speed needle is the most commonly used fine-tuning device, by controlling the length of the balance wheel speed control frequency, the advantage is to adjust the wide range, a few minutes can be transferred back, but a long time, will be poor outrageous. No card through the weight of the screw, adjust the balance wheel center of gravity to control the vibration frequency, adjust the time range is very small, usually within a minute, at the factory when the alignment, the use of damage is not very small error, which is currently High-grade tables are used without card structure of the reasons.

Glaxi movement of the gooseneck fine-tuning
German watches are preferred three quarters of the plywood, so pendulum Cartier love bracelet replica plywood becomes the most prominent movement, the most able to move people’s parts. Balance wheel system itself is the focus of movement, and spinner is the focus of the focus. Walking fine-tuning device is the core components of the escapement, and now no card spread the prevalence of hairspring, making the traditional speed of the needle but become a low-end feeling, but the speed needle plus gooseneck fine-tuning situation is completely different.
Glashütte European Patent EP 1437634, inventor MATHIAS HINTZE HANS-GEORG SCHN, filed on December 19, 2002. This patent is subject to a patent examination, giving only two pieces of A background technology contrast literature, successfully obtained authorization.

For the use of this fine-tuning device of the table to adjust the alignment, through 4 steps to complete:
1, positioning, loosening the screw 19 to open the claws secured to the half of the balance plate 10, and releasing the screw 9 through the speed needle 20 for a wide range of coarse adjustment. And then finely adjusted by the screw 7 on the fastening needle 20a. Tighten the screws 9 and tighten the screws.
2, the watch will wear a number of positions, high-end table have been adjusted by 5 directions, that is, isochronous adjustment, Glashütte’s gooseneck fine-tuning is also designed to adjust the timing of the way, loosen the screw 29 to open the fixed To the jaws on the jerk 20, and then loosen the screws 9. Then, by changing the fixing angle of the gossamer 4 by manipulating the trimming screw 7, the timing is optimized. Tighten the screw 9 after completion, then tighten the screw 29.
3. Adjust the travel time using the balance screws 2a and 2b that change the moment of inertia of the balance wheel.
4, Trim, Loosen the screws 29 Open the jaws fixed to the jerk 20 and release the screws 9. Use screw 7 for fine adjustment. It is advisable to tighten the screws 9 first and tighten the screws. The best step can be adjusted within a few seconds to go.
Mineral crystal glass table mirror is a kind of watch mirror material, usually ordinary Cartier love ring replica crystal glass polishing and then strengthen the hardness, but the hardness is still inferior to sapphire crystal mirror. Mineral crystal glass called artificial crystal, due to the rare crystal and not easy to mining, can not meet the needs of people, artificial crystal glass was born. As a result of high permeability, can be made of various crafts and greatly favored by the world. Mineral crystal glass is made of silicon (Silica) and lead oxide (follow-up lead-free crystal using other materials, such as potassium oxide, barium oxide, etc.) together, so that crystal is particularly shiny, clarity is from the grinding technology plus quality.

Mineral crystal glass and synthetic glass
Mineral crystal glass and synthetic glass look very similar, but it is two completely different substances. The main difference is the following five aspects:
1. Material is different: mineral crystal glass is the crystallization of silica, synthetic glass is only a mixture of silica containing the mixture.
2. Different effects: synthetic glass only decorative role, mineral crystal glass in addition to decorative role, there are piezoelectric effect, a special health effects.
3. Price is different: mineral crystal glass unit price than synthetic glass several times or even several times higher.
4. Physical properties are different
(1) mineral crystal glass is a crystal, with a high hardness (Mohs 7), and synthetic glass hardness is low, (Mohs 5.5), mineral crystal glass can be drawn on the synthetic glass traces, and vice versa Can not.
(2) mineral crystal glass is a crystal, thermal conductivity is better, with a tongue licking touch the feeling of cold, synthetic glass is warm.
(3) with a polarizer, mineral crystal glass can light, synthetic glass can not.
(4) high-quality mineral crystal glass facing the light to see, clear and translucent, there is no small Cartier nail bracelet replica bubbles, no water, so expensive. So that the quality of mineral glass grade and price is very relevant.
5. Different processing technology: synthetic glass can be hot cast molding, save the province of labor, low cost. Mineral crystal glass is a crystal, can not be reversed after heating and melting, so can not use hot casting method, can only be used for cutting and other cold processing.
