The cal.3135 movement is a typical Rolex movement. It is a machine built into typical Rolex watches, including the Rolex submariner. I would like to say that the brand value of Rolex is not obtained at all. If you are an operator, you should be able to skillfully overhaul the 3135 movement. But it is also a movement that no one can completely overhaul. Disassembly and assembly are basic and you have to understand the structure and refuel exactly where you need oil.

It is the part that is connected to the automatic weight, but the oil is very hard. Which part is ...

This is where the red arrow in the picture points. It is impossible to check by eye. You have to work closely with a microscope to recognize that. If you work without checking carefully, those parts will not be cleaned properly, and the oiling will not work properly.

Rolex's movement is always beautiful.

Removing the balance wheel

Pallet fork separation Pallet forks are small parts that play a large role in clock operation. It is a part that requires a lot of hands because it has to be coated with oil and oil.

It starts to decompose more and more deeply.

Separation of main spring bridge

Removing the main spring barrel

When I open the barrel, the oil is very hard. It's not such a serious situation, but if you keep it as it is, you will have serious problems, right?

When we look at the watch, it looks like this behind the glass, needle, and dial. It is the front of the movement.

Even if the clock looks clean, there are many times between the lines of the clock. If you fold the bar of your watch and look at the gap, you will see the time. So is the buckle part. This is not because the person wearing it does not manage well, and it occurs naturally because it directly touches the skin of the wrist for a long time. After washing for a long time with an ultrasonic cleaner, the clean water becomes quite dirty. Depending on the condition, you may change the water and wash it again.

Clean the case and at the same time clean the movement.

Hair spring that are thinner than hair are very sensitive, so they are a special target. The balance wheel is said to be the heart of a watch because it constantly stretches and shrinks like a heart during movement.

Cleaning and drying work. Overhaul is generally recognized as a process of disassembly and cleaning.

You need to reassemble cleanly cleaned parts. Stacking the parts on the main plate in order. In the process, oil ring work and epilam coating work are required.

The appearance of oiling the main spring.

Lubricate appropriate oils where needed through an oiler.

Second wheel refueling I am gradually regaining my image. There is a difference between the disassembly order and the assembly order, so simply assembling in that order does not make a complete assembly.

Pallet fork, escapement wheel epilam coating

All parts have a reason for existence. Each has its own role. So the overhaul cannot be perfect without an accurate understanding of the movement at work. [This part is not intended to simply show the movement number 3135.

Once the balance wheel is in place, You must coat and refuel the cap jewelry without fail. It is an essential task, but many watches do not go through this process properly. The result is always the same. Soon the error increases and the reserve function decreases.

Gem assembled in place after epilam coating and oiling

This process is done twice in the same way on the same part located in front of the instrument.

Microscopic view. I said that the 3135 movement is a great machine ... because the machine itself maintains the best performance. If you do the right overhaul, it will stay in top condition. Prerequisites are the most important. 'Right overhaul'

If you lubricate the rotor again ...

The hardened oil in the rotor section that I showed you at first was cleaned cleanly. Since the necessary oil is refueled, the rotor will work well in the future. Since the automatic watch is rotated and charged automatically, this part can be said to play the most basic and important role in the automatic watch. The difference from the sound of the rotor turning after the overhaul ends. Many of you feel the difference and tell me that it sounds when you first buy the watch.
