This week for Tuesday Tools — Oilers. No, not the Houston Oilers or the Edmonton Oilers. When I clean and service a watch one of the most important things is to place the correct amount of oil precisely on the points that need lubrication. I use oilers to place the oil. There are three main […]

Water Tests Explained

Water resistant watches need to be tested or there can be no guarantee that they will perform as they are supposed to. When a watch maker performs a water test the price usually includes the necessary tasks to ensure the watch passes the test but not the parts needed to make it pass, should it […]

A clean watch lasts forever

As a watchmaker I see a lot of watches. Some people are kind to their watches, others really beat them up. Some watches still look brand new when they come in, others are totally covered in scratches. Some watches are nice and clean and others are covered in body cheese. One thing is certain, a […]

Rolex Parachrom Hairspring

It seems there is a lot of mystery surrounding this innovation made by Rolex so I will try and clear it up using two documents of pretty good authority. I wish I could say I had talked to the head of the parachrom department at Rolex but I haven’t. The parachrom hairspring didn’t really start […]

Magnetism – Enemy of Isochronism

Some of the things that affect isochronism include: magnetism, external shocks, friction, and poise of the balance and hairspring. Magnetism is one that you will certainly notice right away. This week I had a customer’s watch come […]

But I just had my watch serviced!

It is very rare that I do a partial repair. When you are inside a watch messing around the only way to guarantee everything is clean as it should be is to completely service the watch. Sometimes when I estimate a full service the customer tells me that they just had their watch serviced, so […]
