Inside a Rolex Submariner with a 3135 Caliber Movment...


Magical Macro

Henk Hoving from Groningen in the Holland (Netherlands) decided to take apart his Stainless Rolex Submariner with the 3135 Caliber Movement to see exactly what makes it tick, and his Macro Shots are Magical. Thanks for sending in the Superb shots Henk!!!

Tip: You must click on all these images to see them close up.

In the photo above and below the winding rotor is still in place.

In the photo above and below we see the hairspring oscillating at 28,800 beats per hour, which is 691,200 beats per day, and 25 Million beats per year. 

Contrast this with a human heart which when at rest beats 70 times a minute, which would be 4200 times an hour, 100,800 beats per day, and 3.7 Million times a year.


Next Henk removed the balance and hairspring, which is the heart of the watch.

Watchmaker and writer/publisher of Watchmakingblog.com, J. Peter points out "The hairspring is the regulating organ which determines the rate at which the balance oscillates in its regular fashion."

You see the 3135 movement below with the balance and hairspring missing.

Now you see the balance, hairspring and rotor removed.


Then Henk gets in really close.

Your use of the term mainspring is not correct. The part you refer to is the balance and hairspring. The mainspring is the power source for the watch housed inside of the barrel which is not visible in any of your pictures. The hairspring is the regulating organ which determines the rate at which the balance oscillates in its regular fashion.

Hi J. Peter,

Thank you for sharing your insight and correction.

I don't know nearly as much about the inside as I do about the outside of Rolex watches, but I sure am learning quickly. I am not a watchmaker, but I find the movements to be beautiful and fascinating.

Hopefully, you will stick around and share much more of your valuable watchmaking insight with us in the future.

Warmest regards,
Jake Ehrlich
