Hi earning luxury club training: Introduction to the movements used in the Longines series

Going back to a long-established watch brand, the first thing to look at in the development of the movement is a one-sided statement, but you have to admit that this is the case. Today's medium and high Swiss watch movements have been unified by several movement manufacturers. The famous ETA movement factory belonging to the Swatch Group is the same as the Longines. The Swiss mid-end watch brand is basically ETA. Sweeping, the self-produced movements of the era of flowers and flowers have become history.

Longines is not sure about the status of today's rivers and lakes. However, its popularity today is not the same as that of skilled craftsmen. The most familiar thing is the long-lasting star effect of Longines. Today, Xiaobian will take you the calibre commonly used in the August 18th Longines.

1, L619.2

Basic movement eta2892, shock frequency 28800/h, diameter 25.6mm, thickness 3.6mm

This movement is no longer familiar, and the main movement of Longines has been this one for more than a decade. In terms of performance, the 2892 calibre is almost perfect, and the power reserve of more than 40 hours is enough for one day. But after jumping out of 2892 and looking at this movement, you will find that Longines has very limited changes to it. Basically, it is to adjust the error. After a little decorative texture, it will be assembled and shipped.

The advantages of this movement are obvious. The stability is even dare to blame the 3135 of the laborer, and the shortcomings are well known. The lower efficiency of the winding makes the white-collar workers in the society feel inconvenient. Because the office does not walk all day, the lack of exercise causes many automatic mechanical watches that use this movement to be manually wound up once every three times.

Models equipped with this movement: L4.721, L4.821, L4.921, L4.774, L4.874, L4.760, L4.860, L4.809, L4.810, L4.910, L2.628 , L2.518, L2.785, L2.763, L2.766, L3.694, L3.695, L3.688, L1.647

2.L888.2

The basic movement eta2892, the frequency is 21600/h, the power reserve is 60h, and the movement type is automatic.

This movement has been mentioned many times frequently, which is the improved version of the above 619.2. Inherited all the clothes of the 2892 movement, and changed to a 60-hour power reserve. The use of more advanced NIVACHOC suspensions on the suspension alone will ensure that there is no high-fibre 888.2 movement on the market. Longines's change is still conscience. After all, there are only a few card-free hairspring movements that can be bought at this price. In fact, 888.2 can find the shadow of the entry Omega in many aspects.

Currently equipped with the movement of the model: L2.793.4, L2.628 (gold), L4.921.4, L4.821.4 (less), L4.860.4 (less), L4.874.4 (less), L4.910.4 is currently in the shop Goods phase.

3.L602.2

Basic movement ETA2897, shock frequency 28800/h, diameter: 25.6 mm, thickness: 4.85 mm

This movement is the component of the 2892 plus power display, the overall structure is the same as the 2892 is also very stable.

Personally, the power display is very practical, because for the 2892 with low efficiency, it is very important to know the remaining power reserve at any time.

Polishing is the same as the 619. It is also a simple ornamentation and adjustment. This movement is carried on both the master and the Paris stud. The existence of the mouth of the basic non-sports office is simply a savior.

My evaluation of this movement is basically the same as that of 619, and the advantages and disadvantages are the same. At present, it is the mainstay of low price.

Models equipped with this movement: L2.708, L2.703, L2.672

4.L693

Basic movement ETA.A07.161, vibration frequency 28800/h, diameter: 36.6mm, thickness: 7.9mm

Conch dynamic display standard movement, eta for the Longines dynamic movement. The basic movement A07.161 was restructured from 7750. The ETA official said that this movement has changed the entire structure of the 7750. This is no nonsense. A good chronograph movement will be dismantled for you. Change the structure? However, this also shows that the movement is indeed a big change. In fact, all A07 and A08 series movements can be called semi-self-produced. From the point of view of polishing, the fish scales with almost no dead ends make people feel conscience.

Currently the model with this movement is only L2.666

5.L678

Basic movement ETA7751, shock frequency 28800/h, diameter: 30mm, thickness: 7.9mm

This movement is too famous, and Xiaobai, who knows nothing, has heard of it being easy to break things.

Let's first list the functions of this movement: basic big three needles, 60 seconds timing, 30 minute timing, 24 hour timing, annual calendar, week, small seconds and moon phase. It is very rare for a piece of watch in the same price to be so luxurious. The problem is that the more features, the more taboos, and the more unstable. Coupled with a lot of sales, followed by a lot of faulty parties.

Card week, card phase phase, solid machine screw break and so on. After all, 80% are because they did not read the instructions or use them carelessly.

Models equipped with this movement: L2.673, L2.798, L2.792.8, etc.

6. Women's movement L595, L592

Basic movement: ETA2000, vibration frequency 28800/h, diameter: 19.4mm, thickness: 3.6mm

Longines' small size movements are rare, of which 592 is a relatively high-end and representative, and is an upgraded version of the 595.

The basic movement ETA2000 of the 592 and 595 is the female version of the ETA2892. Due to the smaller size and one-way winding, the 2000 movement further magnifies the problem of low efficiency of the 2892 winding. Prior to this, in Longines' L592, there were no extra changes other than simple decorative sanding and adjustment. In the L592, the single-winding is changed to two-way, which can alleviate the problem of low efficiency of the winding, avoiding the sneak stop, and the automatic gyro becomes the iconic hollow of the Longines. And in the new version of the 595, the NIVACHOC suspension was also used for the first time, but because the size is too small, the cardless hairspring has not been changed.

The L595 is light and compact, and is also more aesthetically pleasing than the 2671 movement. The new version of the flag 274 also began to use the improved new 595, can be said to be a good combination of appearance and performance. But the shortcoming is still the efficiency of the chain, and female users who don't like to play with watches may be extremely unacceptable.

Models equipped with this movement: L2.128, L2.309, L2.142, L4.778, L2.142, L8.111, L2.263, L2.285, L2.257, L4.278, L3.276 , L2.563 is currently in the new version of the distribution stage

7.GMT dual time zone movement L704

Basic movement: ETAA07171 movement diameter: 36.6 mm movement thickness: 7.9 mm power reserve: 46 hours

This is also the exclusive movement of ETA for Longines. The basic movement is called ETAA07171. It uses the patented heat treatment spiral hairspring. In theory, all A07 series movements are more durable than the ordinary 28XX movement.

Watches equipped with this movement: L2.718, L3.668, L3.669, L3.687, L2.799.L2.778

8.L636.5 double calendar movement

Basic movement: eta2836, frequency: 28800/h, power reserve: 40h

As an old core, its stability is super good, and the parameters are also quite satisfactory, enough for normal use.

The week is the smallest audience in all functions. The price of the movement is cheaper in all Longines. In general, the relatively low price/performance ratio is the truth, but there is no black point in stability.

Model with this movement: L2.755, L4.799

9. Small size movement L593.2 and L591.2

Basic movement: ETA2000-1, movement diameter: 19.4 mm, vibration frequency: 28800/h, power reserve: 40 hours

Although these two models are small-sized movements, they are used in the men's watches of the Jiayu series. In order to make the thinner, the second needle assembly was removed, leaving only two extremely simplified needles.

L593.2 is an old face, and the 708 of the Jiayu series has been used for a long time. The movement's changes are similar to those of the women's models. The simple decorative lines are polished, but because the second hand is removed, the male watch is thinner than the average female watch.

L591.2 is an upgraded version of the 593, and is also an alternative core for the future of the men's Jiayu. Currently mainly used on the Jiayu series 908. The change is similar to the female model 592, which has been changed to a two-way winding and a Breguet shock absorber. Also added size.

Model with this movement: L4.708, L4.908

10.L667.2 chronograph movement

Basic movement: ETA7750 movement diameter: 30 mm movement thickness: 7.9 mm power reserve: 46 hours

This calibre is a Longines-based chronograph movement using the original ETA7750 chronograph movement without much modification. First of all, as the famous timing core of ETA, the 7750 is not only stable and durable, but also very plastic. It can add various functions and even three questions perpetual calendar.

Watches equipped with this movement: L3.673, L3.661, L3.636, L3.644

11.L633.5

Basic movement: ETA2824-2 movement diameter: 25.6 mm movement thickness: 4.6 mm power reserve: 38 hours

The L633.5 was remodeled from the 2824 calibre and is stable and durable in the core. Although the L633.5 uses a cheap core, it is Chronometre grade, which is the high-level 2824 in the group.

Although it is better than the level of the rudder Breitling, it is also relatively cost-effective compared to the part of the blank Sw.

Model with this movement: L3.657, L3.642, L1.611

12. Small three-needle L615.3 movement

The basic movement eta2892 has a vibration frequency of 28800/h, a diameter of 25.6mm and a movement thickness of 4.35 mm.

The low-priced small three-pin in Longines is not bad, and overall it is quite satisfactory. However, most of the matching series are relatively low, and the positioning of this movement is also left at the middle level.

Watches equipped with this movement: L4.804, L4.805, L2.642, L2.731, etc.

13.Cal.L674 double calendar chronograph movement

Basic movement: ETA7750, diameter: 30, thickness: 7.9, frequency: 28,800 times / hour

This is a very unpopular movement. It is very similar to the L667 in sanding. It is also a simple fish scale decoration; it is more than one week in function.

14.CAL.L697 retrograde movement

Basic movement: ETAA07.L11 diameter: 36.6mm thickness: 9mm power reserve: 46 hours

Each of the Longines retrograde movements is a relatively stable and complex movement with a weekly display, timing reversal, power reserve, and date. They all made a retrograde, but based on the powerful performance and high stability of the A07 calibre, this movement has almost no damage from the current feedback.

The watch with this movement: the master series L2.714 and L2.716.

15.L688.2 column wheel chronograph movement

Basic movement: ETAA08.231, movement diameter: 30 mm, movement thickness: 7.9 mm

Models equipped with this movement: L2.733, L2.743, L2.744, L2.784, L2.754, L2.750, L2.800, L2.759
