Rate Adjustment Longines 844.4

Can anybody shed some light on the question of if the lever mechanism on this escapement can be used to adjust the rate of the movement, or only the beat error? Do the screws on the balance wheels only control the posing of the balance wheel or do they…

Where do I even begin…

To keep it brisk, my main attraction to horology is the mechanical aspect. A mechanical aspect that I’m semi knowledgeable in, but want to dive into as deep as possible.

Anyone got any recommendations on a fully comprehensive kit/combination of kits? Not just a few screwdrivers and some rodico, I mean everything from that down to crystal pushers and pressure testers.

The end goal is to restore vintage pieces myself, for my collection and my friends/colleagues (and hey, maybe some of you…

Curved tweezers?

I’ve been wanting to try curved tweezers for awhile, and to be honest I held back because The cost, and I already have multiple pairs of regular straight ones.

I finally get the chance to see how they feel, and I hope they are worth it. I found a set of brass curved tweezers from Italy.

Does anyone else use curved, and how do they feel compared to straight? I know the huge difference will be how to hold them and grip small items (of course). Guess I’m feeling a bit leery about my first…

Tissot Seastar stops working when hands are attached

Dear community,

I’m very new to this universe of watch making/restoring. I’m getting my hands fixing and restoring simple movements and i have a situation recently that I cannot find the root cause and would love to get some advice from experienced watchmakers from this forum 😉

I’m trying to fix an automatic Tissot Seastar.
The watch works totally fine when the hands are off. Ticks very well and very precise.
As soon as I mount/attach the hands again, the balance weeks slows a lot and…

Help me finished my half baked dial?

Hello all!

I have been building “Seiko mods” of late with AliExpress sourced parts. (Successfully, lol)

Stupidly, I got a dumb idea in my head to build a watch based on a VK67 mechaquartz….but unfortunately there are no dials available. Let’s make one, “how hard can it be?”, lol

I’m an engineer by trade and have a nice home workshop/machine shop…but it’s not exactly tailored to making small stuff.

I’ve spent the last few weeks messing about with my CNC router and came up with this…

Making a GMT hand into a minute hand

Without any backstory, I need to make a GMT hand to work as a minute hand on a NH35 movement. I think my plan is to cut the hand off a minute hand ring but leaving a slight bit on the ring, then cut the ring off the GMT hand and cement it onto the stub…

Help Replacing Crystal in Bulova Hack A-11

My wife’s favorite watch has been her Bulova A-11 Hack Watch (Model 96A282), a contemporary tribute to the original A-11 — stock photo below. However, she broke the crystal. Citizen Watch Group (which includes Bulova support) said they can’t sell me a replacement part because they are out of stock for at least six months, and I would need to mail it in for service. However the watch is no longer under warranty, and I’d just like to replace the crystal myself.

Unfortunately, I’m not…

When the watchmaking tools include a socket set….

Important safety edit: Wear gloves or use nice block of soft wood if you’re using sockets to get the crystal out. I’m still feeling a couple of lugs in my palm, 24 hrs later.

Your reminder that sometimes automotive tools can help fix watches.

Had some fun on the work bench this long weekend with a vintage “VaLaire” 21 Jewel Super DatOMatic (by Mortima) dive watch that I (predictably) picked up at an online auction…and without considering the hints as to the size (the case is only…

Long term storage of gaskets

I have a watch that I love (a Grand Seiko) and I would like for it to stay waterproof for as long as possible. It is getting somewhat long in the tooth, and I know that after 30 years parts – especially gaskets – will become hard to find.

I have a few…
