How long does it take to produce a watch?

There was another thread were I had discussed how many watches are made per employee each, for different major brands.
I thought it would make it more relatable to figure out how long it takes to produce one watch based on a companies annual production and number of employees.

I could not use several fine watch companies, because the produced jewelry as well and could not find the number of employees that were exclusive to watches. Such as Breguet, Bvlgari and Chopard.
I understand that this is not perfect, it does not take into consideration companies that have the plates created by another company, like Gronefeld or companies that make parts for other companies like Voutilainen.

I received all my information from google searches, no professional newsletter.
I listed the producer, the number of watches they produce each year, the number of employees, how many watches the company produces per employee/per year, and finally what that would translate into how long it would take one employee to produce one watch.

And here are the results:
