How do you find lift angle?
You can figure out the lift angle if you already know the amplitude. Mark one of the balance arms, so you know its position in rest. Then, slowly increase the power in the mainspring with one click of the crown at a time until you see that the balance wheel has an amplitude of 180 degrees.
What is the lift angle of a watch?
between 48 and 54 degrees
The lift angle of a watch refers to the distance from when the pallet fork and impulse pin come in contact detaches from the escape wheel to when the escape wheel meets the pallet fork. Typically between 48 and 54 degrees, the ideal number is provided by the movement manufacturer.
What is an acceptable beat error for a watch?
A beat error lower than 0.6ms is considered acceptable. If adjustment is needed, turn the watch over to its back and open the case back to access the back of the movement.
What is a left angle?
3) A left angle is when the base ray is pointing left instead of right. 4) A left angle is 1/2 of a straight angle, like when it is cut into two pieces, only it is the part on the left, not the part on the right.
What is a good amplitude for a watch?
A healthy movement should, at full wound, have a high amplitude, in the range of 280-320. A low amplitude generally indicates problems that needs to be fixed prior to regulation, like obstruction due to foreign elements, oil drying up, etc. But anything above 250 degrees can still be considered healthy amplitude.
Does watch beat error matter?
A high beat error prevents the watch from self starting i.e. it does not start running by itself when wound from a unwound state, and requires you to swing the watch to start running. An exceedingly high beat error, on the other hand, can cause a problem called “rebanking” or even stop a movement.
How do I make my automatic watch more accurate?
Put your watch vertically on the case size as well, but here with the crown on top. This action will help you slowing down the watch. So, in order to regulate the accuracy of your watch, depending on the three cases, simply place your watch in the correct direction on your night table before sleeping.
What are the 5 types of angle?
How to measure Different Types of Angles?
- Acute Angle. An angle which measures less than 90° is called an acute angle.
- Right Angle. An angle which measures exactly 90° is called a right angle.
- Obtuse Angle.
- Straight Angle.
- Reflex Angle.
- Complementary & Supplementary Angles.
Why is a degree 90?
If the value of the angle between the horizontal and vertical lines is exactly equal to 90 degrees, then the angle is called a 90-degree angle….90 Degree Angle.

Can watch amplitude be too high?
Watches with low amplitude generally lose time. High Amplitude – High amplitude can cause what is known as knocking the banking. This can cause damage to the roller jewel from knocking against the other side of the pallet fork.
When should you not adjust an automatic watch?
You should not make adjustments – such as setting the date or day of the week – when the time on the watch reads between the hours of 9:00 pm and 3:00 am. Each movement has its own guidelines so this may vary a little, but avoiding setting anything a few hours either side of midnight should keep you out of trouble.
How many seconds a day should an automatic watch lose?
The general rule for mechanical watches is that a deviation of 10 seconds or less per day is good.
What is a lift angle?
The angle that the balance wheel travelled between the first and third noise is called the “lift angle”. The lift angle is a geometric feature of a movement. This angle is given by the movement’s manufacturer.
What is the lift angle of a balance wheel?
The third and loudest noise is created when the escape-wheel meets the pallet. The angle that the balance wheel travelled between the first and third noise is called the “lift angle”. The lift angle is a geometric feature of a movement. This angle is given by the movement’s manufacturer.
What is the best lift angle for a watch?
Most common lift angles of movements are between 48 and 54 degrees. If you don’t know the exact lift angle of your watch, we suggest giving the default lift angle of 52 degrees.
