What is the difference between an integrated movement and modular movement?

Hi guys,

Just have a quick question about the difference between an integrated movement and a modular movement.

I am looking specificially at the difference between the movements of Tonda PF Sport Chronograph and Tonda PF Chronograph.

Both watches use the same caliber, but one houses an integrated movement while another houses a modular movement.

What exactly is the difference between the two, given that the two watches uses the same caliber?

Thanks in advance!

A modular chronograph is when the chrono portion of the movement is attached to a base caliber often adding significant thickness to the movement overall. A famous application would be the Royal oak offshore for many years using the Dubois-Depraz module.

Generally speaking an integrated chronograph movement is always preferred. It’s engineered from the ground up and there are advantages in overall size and sometimes appearance.

From my understanding neither of the current pf chronos are modular.

Why not ask in the correct forum this is the Rolex/Tudor watch forum.

As said a modular chronograph is just a module which sits on top of a movement, it is not built in. Generally, you can see it as the chronograph pushers will not be on the same plane as the winding stem resulting in an overall thickness increase. I am not sure one is better than the other. I suspect a modular type is easier to service.

The modules themselves are a service nightmare, they get discarted and replaced with a new module if it needs service.

An integrated chrono is the only proper way IMO, I'd never get a chronograph with a module.
