While i have UN on my list, i know which movements in the watches are.
I have no Macbook Pro, in my house is a Macbook Pro of a family member.
My iPhone is magnetic incl the sleeve.
When i go to bed i put not any of my automatic watches on my Apple magnetic sleeve. Only my Longines quartz watch, and i read a quartz watch is also sensitive for magnetic fields.
The UN movements UN815 and UN820.
The basic Ulysse Nardin caliber and magnetism.
Dear friends, I have recently reported in the "main" forum that the magnetic field generated by a MacBook Pro laptop is around 1000 Gauss (I have used a professional gauss-meter). Is this safe with a watch using the UN-118 caliber ? I know that the hairsp...
I think modern movements are quite antimagnetic
I also have MacBook pro and don't have any problems with modern movements. Even the movements with regular hairspring like the ones in UN perpetuals don't seem to be having any issues. That being said the one which is clearly siceptable to laptop's magnet...

I have 10 different brands of watches and Apples array of toys...
and have never had any magnetic issues. My cheap de-magnetizer is covered with dust. My pacemaker, on the other hand...........just kidding.
I have been using my 2012 macbook pro
for 10 years now daily in school and in university now. I have primarily worn vintage watches from the 1950's to 1970's daily, and I have never had one get magnetized. I would be on my laptop for several hours daily, and for the past couple of years as mu...
It is only the hairspring
The negative effect of magnetism on watches comes almost exclusively from its influence on the hairspring. A "magnetized" hairspring tends to stick to its coils effective making the spring shorter, hence making the watch run faster. Non magnetic i.e. sili...
