Q: Why can’t the “crown” be pulled out?

 

That’s because it is the screw-in crown, which runs as follows: the “crown” which is made into a “nut” will turn to the “0” gear after it is screwed out by rotating it counterclockwise (if you rotate it clockwise, you are winding the watch up manually). Set the date with the “1” gear and the time with the “2” gear. After the time has been set, rotate the crown clockwise, screw it in and lock it to keep it out of water!

 

 

Q: How to set the time and date of a watch?

 

First, pull the “crown” out. Set the date with the “1” gear and the time with the “2” gear. (If it has been screwed in, please rotate it counterclockwise first to screw it out)

 

Points for attention when setting it:

 

1. For a watch with a screw-in crown, do not force the crown to be pulled out. Please rotate the crown counterclockwise to screw it out first. After the time has been set, rotate it clockwise, screw it in and lock it to keep it out of water!

 

2. Secondly, for a mechanical watch, do not set the week and calendar at any time from 9:00 p.m. to 4:00 a.m., otherwise, its movement may be damaged.

 

3. Do not set the time counterclockwise at any time from 9:00 p.m. to 3:00 a.m., during which the week and calendar gears are switching. In the event of a long-term counterclockwise setting, the internal parts will be damaged. In other time periods except the above, it can be set either clockwise or counterclockwise freely.

 

 

Q: Why is the date wrong?

 

The date of a watch will jump over one space every 24 hours. If it fails to jump over it in the morning, it will do so at noon the next day, in which case it will be 12 hours slower and you need to manually rotate the hour hand once. If the date jumps over a space in advance, please set it back to the previous day first and then set the date to the correct day.

 

 

Q: What’s the daily rate of a mechanical watch?

According to the regulations of the watch industry, the normal daily rate of a mechanical watch of the international standard falls within ± 30 secs. Ours has been controlled within 10 secs generally by having it tested with the instrument before delivery.

 

 

Q: What’s the daily rate of a mechanical watch and a quartz watch respectively?

 

Quartz watches are highly accurate because their daily rate falls within 0.5 secs.

The daily rate of a mechanical watch is up to the quality of its movement.

The daily rate of homemade ordinary mechanical watches falls within 50 secs, generally around 10 secs to 20 secs.

The daily rate of Seagull movement, CITIZEN movement and Swiss ETA movement falls within 30 secs, generally around 10 secs. Some who are green hands of mechanical watches are shocked by the daily rate of 30 secs, that is, there will be an error of three and a half minutes in a week. Please note that there won’t be a daily rate of 30 secs every day. It may be the case that there is a daily rate of a few secs or more than ten secs, both below 30. The daily rate will be detected, corrected and controlled within 10 secs before delivery by YiChen Watch.

 

The accuracy of a mechanical watch is mainly determined by the stability of the oscillation period of its balance hairspring, which will be affected by five factors:

 

1. The range of oscillation: the oscillation of the balance wheel will be directly affected by the tightness of the spring. The tighter the spring is, the more accurately it goes. Therefore, in the event of insufficient wrist movement when wearing it at ordinary times, you are recommended to replenish the kinetic energy manually.

 

2. Changes in positions: mainly changes horizontally (watch dial upward and downward respectively) and changes vertically (crown downward, towards the left and upward respectively). If you wear the watch correctly, the crown won’t face toward the right. In this way, there are five changes in positions in total. The oscillation period of the balance hairspring system of a watch will be affected by the changes in positions.

 

3. Impact shock: the oscillation period of the balance wheel will also be influenced by the severe impact shock, especially for mechanical watches with a small range of oscillation or low frequency.

 

4. The magnetic field: many parts of the movement of mechanical watches are made of steel, which are more likely to be magnetized.

 

5. Changes in temperature: with changes in temperature, the geometric dimensions of the balance wheel and hairspring will also change. Even the tiniest change in these key components will impose a direct impact on the oscillation period.

 

6. There will be a 2-month run-in period for mechanical watches. The true daily rate couldn’t be observed without having passed the run-in period. Those with high daily rates can be returned for rectification for free.

 

Its accuracy will also be affected by some other factors, such as the watch case that isn’t properly sealed being filled with vapor, or there being a speck of dust in the watch.

 

In short, for a mechanical watch with higher accuracy, its string should be pulled as tightly as possible. Generally, a watch runs better when it is placed horizontally than vertically. Please keep it away from the magnetic field and water and prevent it from breaking.

 

 

Q: What’s the difference between the crocodile strap and the calfskin strap?

Compared with the calfskin strap, the crocodile strap looks more glossy and fuller. Besides, the latter is characterized by higher durability, softness, high breathable performance, coziness and the like.

 

 

Q: How about the Citizen 9015 movement?

The 9015 is the original Citizen movement, which is superior to the Seagull movement and close to the Swiss ETA movement in terms of performance. At present, the majority of the top movements (knockoff movements) in the market are refitted on the basis of the Citizen 9015 movement, the only disadvantage of which lies in it being slightly noisy.

 

 

Q: How about the Seagull movement?

 

The most frequently used movement of knockoff watches includes the Seagull movement and the Citizen movement. The former can be called to be the top-notch homemade movement, which is a knockoff of the Swiss movement and thus highly resembles it in appearance design. In the early years, watches with Seagull movements were claimed to be ones with Swiss movements by many suppliers.

 

The “Seagull” brand, born in 1955, has a history of 64 years. Being the birthplace of the first mechanical watch in China, it has grown into the largest production base of mechanical watches and movements in China. With such a background, its movements will be surely of superior quality.

 

 

Q: Are they Swiss movements?

 

A: It’s hard to give a definite answer. It is claimed by many suppliers in the market that Swiss movements are adopted by their watches. Some customers will ask, “Why aren’t Swiss movements used by your watches?”. Then I will be absent-minded and have no idea about how to explain it. In the knockoff watch market, there are very few models coming with genuine Swiss movements when leaving the factory. Seagull movements are knockoff Swiss movements, which are called Swiss movements by sellers of the same trade. Some small green hand sellers who have no knowledge of this will tell customers that they are imported Swiss movements.

 

The main reason why these watches don’t come with the Swiss movements when leaving the factory is that the Swiss movement is too costly. Models with Swiss movements are sold at about 3,000 and above, thus, they are in limited demand and there will be an overstocking issue. Therefore, they aren’t cost-effective. If you need models with Swiss movements, some of them can be provided for you at additional charges. The original watches are designed with 2824 or 2836 or 2892 movement, all of which can be replaced by Swiss ETA movement with additional charges. (Because only movements of these three models can be replaced by Swiss movements, and those of other models cannot because of differences in sizes).

 

By the way, as mentioned above, there are indeed a few manufacturers who produce watches that are equipped with Swiss movements, such as the gold filled Rolex from factory C and Longines master from factory KZ. Whether it is with Swiss movement will be clarified by our customer service staff, and we will never sell seconds at the best quality prices.

 

 

 

 

Usage and Maintenance of Chronographs

 

Timing methods

 

The upper button of a chronograph is for timing on/off, and the lower button is for timing reset.

 

Step 1: press down the timing button and start timing, then, the second hand goes forward; the second hand goes forward by one lap, and the minute hand goes forward by one space; the minute hand goes forward by one lap, and the hour hand goes forward by one space.

 

Step 2: Press down the timing button again and stop timing. Check the timing reading from the index indicated by the second hand and the time dial.

 

Step 3: After the timing is finished, press the reset button down to reset the chronograph.

 

Usage of a Chronograph

 

Timing should be carried out following the operation sequence as mentioned above, that is, start timing – stop timing – reset to zero. In particular, as far as mechanical chronographs are concerned, do not press the timing button too frequently. The on/off button is usually more rigid to press than the reset button, especially for new chronographs, because there are many gear parts in a mechanical watch. As long as the timing is carried out following the correct sequence, the chance for gear wear and failure rate will be much lower, which will be conducive to the maintenance of the movement.

 

Prevent the chronograph, especially a mechanical one, from fierce collision, because the more gear parts there are, the higher the failure rate there will be. When timing is on, most of the gear parts of the movement will be running, which will be misplaced in case of fierce collision and thereby leading to failure.

 

It is recommended not to keep a chronograph on constantly, that is, do not keep timing on constantly. Because the second hand will stay still before the timing of a chronograph is activated, some prefer keeping timing on constantly after it is activated so that the second hand could keep running, which will make the chronograph seems to “be running”. Otherwise, the chronograph would be claimed as “having stopped” by others. But in fact, this will be harmful to it. If the timing of a mechanical chronograph is kept on constantly, it will impose a negative impact on the travel time accuracy and energy output of the spring. It is not recommended to keep quartz chronographs on constantly as well. The second hand and the small hand are driven by two stepper motors respectively, which will consume much more power if they are running simultaneously. The service life of the battery of a quartz chronograph will be 3-4 years if the chronograph is used properly; but if the timing is kept on all the time, the battery will get fully drained in less than half a year.

 

Mechanical chronographs are multi-functional mechanical watches. Being one of the symbols of high-end wristwatches, they are quite expensive. Merely the second hand of a chronograph will stay still when pointing toward 12 o’clock. It’s only the second hands of cheap multi-eye watches without timing functions that will keep going forward. So those who know watches won’t start timing if there is no need for it in case that their watches seem to be quite “cheap”.

 

Please feel free to contact our customer service staff for the usage of other multi-functional watches.
