This is actually harder than it looks, the main thing is getting the right file (single cut only), practicing draw filing with minimal pressure, standing up the rod at a low height in the vice, and exactly straight every time. Easy to learn, difficult to master

Some filing practice today. Filing these steel rods flat enough to stand up on their own.

Pic 1 is the set up, bench vice and no. 1 file. Pic 2 is before, Pic 3 after, and pic 4 is the finished article with both rods filed flat

Is it common sense to treat a subject like this as a political football? Do you think this poster was a good idea?

Another vintage tool I picked up. This Seitz jewelling tool is more versatile than it's modern Chinese counterpart. It will allow me to not only replace jewels, but ream worn out jewel settings so they can be either rebushed or their jewels replaced

One bad habit I have is when I'm doing easier work like this I forget to tidy as I go. So here is my bench after finishing today's work - everything on it was used at least once during the assembly of these watches

I cover some of the challenges in selecting the designs for these watches on my IG for those interested

Assembled these custom watches for a couple of friends of mine

Hairspring progress thus far. Someone had clearly tried and failed to move the regulator, bending the hairspring around the stud. Hairspring work is among the most difficult tasks in watchmaking, one false move can wreck hours of progress
October 22, 2025 at 3:00 PM
With disassembly complete the next step is to attempt to fix the hairspring, order a new mainspring, then clean, reassemble and relubricate the movement.
October 22, 2025 at 12:01 PM
This was due to the mainspring being broken.
October 22, 2025 at 12:01 PM
Upon further disassembly more issues became apparent. The movement's winding system was not winding the barrel and thus no power was being delivered

Today's work: this Roamer Searock Automatic features a MST 522 movement (meaning the watch is around 50 years old). It currently isn't running. Upon opening it was very evident why - the hairspring is bent and the movement has been drenched in oil

See this IG post for a more detailed breakdown of what I did during this service

Finished the service on this Seiko. It features one of my favourite day/date quick change mechanisms, to change the date you press the crown, with a long press the change the day

The regulation was trickier than the NH35 as, the 6119C's regulating pins are fixed meaning the only way to change the hairspring length is by moving the regulator. I was able to achieve a delta of +/-11, which is better than the standard +/-20

Today I'm finishing up this Seiko 6119C for a friend of mine. Since the watch is from 1976 parts are scarce, where a NH35 (the modern Seiko workhorse movement) costs £40 today, a replacement 6119C balance alone costs £60 and had to be imported from Palestine

Jenrick casting 1980s British football hooliganism as something that was easily dealt with by police and not an era defining issue which we're still living with the consequences of today... He's genuinely the most unserious person in British politics rn

These are very cheap movements (£40ish) and are therefore much harder to regulate well than Swiss movements. +/-20 seconds per day is within spec, I managed - with much cajoling - to get this one down to an average rate of 10

Some of today's work, regulating a Seiko NH35 movement (as featured in Trump's watches)

More vintage mechanical watches for sale via my eBay.

The Phenix features a rare German Buser movement.

The Rila is a great example of how brass wears over time (my guess would be 50-60 years) compared to stainless steel
