Engraving table daily maintenance guide
Although the movement and material of the replica watch are close to the genuine product, there is still a gap in process accuracy and durability. Scientific daily maintenance can extend its life from 3-5 years to 8-10 years . Based on the practical experience of watchmakers and laboratory data, this paper summarizes 5 core techniques, and attached a list of periodic table maintenance and tools to help users maintain the performance of duplicate table at low cost.
1. Regular cleaning: Avoid dust and sweat erosion
The sealing of the replica table is generally weaker than the genuine product (waterproof grade is more than 30 meters life waterproof), and sweat and dust are easy to penetrate the case when worn daily, resulting in oxidation of the movement or gear jam.
1.1 Procedure
1. soft brush + non-woven : clean the gap of the case with a soft brush every week, and wipe the strap with a non-woven cloth dipped in distilled water;
2. ultrasonic cleaning : Metal watch band every 3 months with ultrasonic cleaning machine (40℃ warm water + neutral detergent) treatment for 10 minutes;
3. waterproof test : After cleaning, use a pressure tester to test the crown seal ring (pressure value shall be ≥3ATM).

2. Winding and timing specifications: reduce the risk of movement loss
The gear material of the replica watch movement is mostly domestic brass, and the hardness is 15%-20% lower than that of the genuine Swiss product, and the wrong operation can easily lead to the gear breaking or the calendar module damage.
2.1 Key No-Nos
1. automatic movement : Avoid manual repair chain more than 30 turns (Seagull 2824/ Cittie 9015 movement);
2. timing function : Do not press the return to zero key directly after starting the chronograph (stop the timing first);
3. calendar adjustment : 20:00 p.m. to 4:00 a.m. Fast calendar adjustment is prohibited (prompt jump mechanism may get stuck).

3. Waterproof performance maintenance: seal ring and crown maintenance
The attenuation rate of waterproof performance of replica watches is 3 times that of genuine ones, mainly due to the lack of crown thread accuracy (tolerance ±0.05mm) and aging of rubber rings.
3.1 Maintenance policy
1. silicone grease : Apply a small amount of silicone grease to crown threads every 6 months (Dow Corning DC4);
2. sealing ring replacement : It is recommended to replace the crown and bottom cover sealing ring every 2 years (cost about ¥50/ set);
3. After contact with water : immediately blot the case with a dry soft cloth to avoid moisture residue.

4. Storage environment control: temperature, humidity and anti-magnetic management
The magnetic resistance of the engraved watch movement is generally lower than the genuine 50%-70%, and the fluctuation of temperature and humidity can easily lead to the deterioration of lubricating oil.
4.1 deposit specification
1. Temperature and humidity : the best environment is 20℃-25℃, humidity 40%-60% (need to avoid light);
2. anti-magnetic : away from mobile phones, audio and other strong magnetic field sources (distance > 30cm);
3. long-term shutdown : manual winding movement needs to be repaired once a month to keep the gear running.

5. Professional maintenance cycle: lubrication and precision calibration
The recommended maintenance frequency of duplicate watch movement is 2 years/time (5-8 years/time for genuine products), because the durability of domestic lubricating oil is poor.
5.1 maintenance process
1. complete disassembly : Separate the movement parts using the Bergeon 6767-F tool set;
2. ultrasonic cleaning : clean gear and splint with aviation kerosene;
3. re-lubricate : Apply Moebius 9010 oil to key points such as spring box and escapement fork;
4. Error calibration : calibration instrument test azimuth difference (controlled within ±10 seconds/day).

6. Conclusion: The feasibility of extending the life of duplicate engraving at low cost
Through standardized operation (such as avoiding the calendar exclusion zone), regular cleaning (ultrasonic cleaning of the metal strap) and professional maintenance (2 years/movement lubrication), the reproduction watch can completely break through the stereotype of “cheap and vulnerable”. Combined with the annual maintenance budget allocation in Table 3, users can achieve the long-term use value of mechanical watches at the annual cost of ¥300-500 yuan .
