Instructions for using Longines watches

　　The ingenious design of Longines watches perfectly combines sport and elegance, and owning a Longines watch is the dream of many watch enthusiasts. So after purchasing a Longines watch, how should we use it correctly? Below, the editor shares the instructions for using Longines watches for your reference.

　　Longines watch instructions: Longines watch structure

　　1. Transmission structure form: the Longines transmission structure is a centre direct-drive double triple-wheel structure, with the centre wheel disc located below the barrel arbor. The double triple-wheel structure is actually similar to the seconds-spring structure, except that the seconds wheel component is moved away from the centre, leaving only the seconds pinion at the centre. To prevent seconds hand jitter, it is best to avoid using a seconds spring to press or support the seconds pinion. Longines waterproof watch 6952 movements adopt a double triple-wheel structure to overcome seconds hand jitter. The so-called double triple-wheel actually consists of multiple parts in the triple-wheel component; the triple-wheel disc 3 and triple-wheel pinion 5 fit together and can rotate relative to each other; the triple-wheel disc 2 and triple-wheel pinion are press-fitted, separated by a gasket 1, and do not affect each other during transmission, where the power of the barrel assembly is transmitted to the triple-wheel component via the second-wheel component. The movable triple-wheel disc meshes simultaneously with the fourth-wheel pinion and seconds pinion; whereas the fixed triple-wheel disc meshes only with the seconds pinion. Due to the gears mutually locking, torque is actually transmitted to the fourth-wheel component via the fixed triple-wheel disc, seconds pinion, and movable triple-wheel disc. The stable vibration time generated by the balance spring component is transmitted via the escapement mechanism, fourth-wheel component, and movable triple-wheel disc to the seconds pinion to indicate the seconds. The two triple-wheel discs lock the seconds pinion while meshing simultaneously, so the seconds hand will not experience jitter.

　　2. Movement architecture, Longines watch movement dimensions (12*1/2 lignes), the maximum diameter of the Longines movement is 28.50 mm. The assembly diameter is 28.0 mm, with a thickness of 4.0 mm.

　　3. Balance spring system structure, the vibration frequency of this movement is 28, 800 vph, and the balance wheel diameter is relatively small, approximately 9.6 mm. It adopts a movable outer stud ring. A micro-regulator device is arranged on the outer stud ring 1, consisting of a regulating disc and a regulating screw. When in use, simply turn the regulating screw with a screwdriver, which drives the regulating disc. Relying on the axial tightening frictional torque between the regulating disc and the regulator assembly, the regulator assembly is made to rotate slightly around the shock absorber, lengthening or shortening the active length of the balance spring, thereby achieving the purpose of finely adjusting the running speed of the watch. The inner end of the balance spring is a triangular inner stud, with a left-handed balance spring. The outer stud differs from the traditional structure. The outer stud screw 5375 and the outer stud plate 376 are used to clamp the outer end of the balance spring, overcoming defects such as Armani watches having poorly secured adhesive and falling off due to the aging of the glue over time.

　　Longines watch instructions: Time-setting method

　　1, pull the crown out to the second position to adjust the time.

　　2, avoid adjusting the time and watch functions between 23:00 in the evening and 5:00 in the early morning, so as not to damage the components of the Longines watch.

　　3, winding the crown upwards when it is not pulled out winds the mainspring. For a new Longines watch or one that has been left unused for a long time, it is recommended to wind it about 30 times. This provides the watch with a power reserve, preventing stoppage or inaccurate timekeeping due to insufficient wrist movement.

　　4, pulling the crown out to the first click adjusts the date, 1-31 days. If you encounter a month with only 30 days, you need to manually advance past the 31th. (Note that the calendar changes at 12 in the evening; if adjusting the calendar during the day, simply rotate the time forward by 12 hours manually).

　　Longines watch instructions: Maintenance method

　　1, regular servicing: Like other precision timepieces, your Longines watch requires periodic inspection and maintenance. Please take your watch to a Longines service centre for inspection every two years.

　　2, water resistance: after a heavy impact, the water-resistance performance of a watch may be affected. Therefore, if you plan on a diving trip, you should have the water resistance of your Longines watch checked at a service centre beforehand. If the case has been opened, the water-resistant seals of the case, dial glass, and crown should be carefully checked, and if found to be damaged, they should be replaced immediately.

　　Longines watch instructions: Precautions

　　Routine care generally protects only the exterior of the watch; internal servicing should be left to professional technicians.

　　Prevent perspiration and moisture from entering the case. Before wearing an authentic Longines watch, wipe the case clean and apply an even layer of clear nail polish. Once dry, this protects the finish from wear and adds surface lustre, helping maintain its value.

　　Avoid using the watch in hot baths, saunas, or environments with drastic temperature changes. Except for 200-metre water-resistant watches, do not wear other water-resistance categories for swimming. The case, bracelet, and crown must be cleaned frequently and kept clean. You can wash them with warm water and then dry them.
