I rather suspect that they worked by daylight, and when it got dark they shut up shop and did something else, but that's just a guess :)
In the days before mass production, I think every part was made by hand, even individual screws.
If you have not seen Clickspring on YouTube, he (Chris) has recently been attempting to recreate the manufacturing methods used by the ancients 2000 years ago to construct intricate mechanisms. It's fascinating what smart minds were able to do with limited resources.

i will look him up.
The workers who made parts were not considered craftsmen. They worked in their homes and in the UK and in that period interior lighting was highly dependent on the sun, and daylight hours are more limited than in most of the USA. This fact even draws into question many battle accounts, especially in Scotland which is even further north.
A lot of work (such as making fusee chains; 1/100th scale bicycle chains) was poor house work.
In chronometers, a "maker" such as Mercer would make the rounds and collect screws, detents, pinions, jewels wetc from people who had no idea what the parts they made were to be used in. Then the parts would be assembled and finished into a working chronometer. The "art" was all in the balance assembly and balance spring. It could take a year before it was ready for trials at Kew.
Early on, jewel making was a national secret. I think it held for 25 years or so.

After dark they made babies so as to have a replacement generation in some years.
Unfortunately, with Netflix, social platforms, etc. , the art of making babies is becoming a thing of the past and I hear they even have to explain it in schools. And still, birth rates keep falling.

Engineering used to be about problem solving, figuring it out. Like doing a crossword puzzle. You never worried, just kept chipping away and learning. Some searching, the right keywords and I can somewhat understand the machine enough to help a bit. Physics, MecE, EE (multidiscipline) knowledge needed for this Tempo make it difficult.
Today, young engineers literally have a panic attack if they don't know something. There seems to be a stigma with "not knowing", even in business and management. I find it funny, being free of such worry. Electronics gives a constant humiliation for those types of people, the "know it all" types especially.
If you don't know enough, then ask - I've learned to reach out to manufacturers and sometimes they have great expertise.

I am so frigging tired of people who WANT to fail. So I passed on your post to both of the service businesses; the one responded saying emphatically that you cannot buy donuts! Have not heard back from the person who actually bought all of L&Rs inventory. He is likely much more confident.
That is what people told me before I had all the breakable parts for the Hamiltn M21 made and 100s of mainsprings for my bread and butter aircraft clocks. Paid those back 5 times over in the last 30 years.
Most people are too damned timid to seize an opportunity. They say "no" when a life altering adventure is right in front of them. In all my years, I have encountered very few ventures or adventures where saying "yes" resulted in my death. Most of my regrets involve saying "no".
Fortune favors the bold. While the meek may inherit the earth, nothing was said about the timid!

There is a revelation that came to me somewhat late in life.
As a child, whenever I needed a widget for some project I might be working on, I would think "Where can I buy such a widget?" Only later, did it become apparent to me that if you need a one-off widget of a particular size and dimension, well maybe you could make it. For me, it was like, "Oh...you can make a thing? You don't always have to buy it?"
