I'm a security researcher with a federal contractor. I basically look for exploitable flaws in systems. My specialty is embedded and control systems. I also have some background in nuclear physics as one of the big tasks I work is assessment of nuclear systems. The education really helps getting my foot into the door to look at systems they wouldn't normally allow access to.

As for background I'm a former US Navy submariner who served a tour on a fast attack boat and then became a rider which means a specialist who went to boats as needed. I worked in unmanned vehicles and submersibles after that. I was selected for the cyberwarfare rating and did that for the rest of my Navy career. I've been mostly contracting since then.

As a kid I use to take just about anything I could get my hands on apart. One particular fascination, much to my family's dismay, was clocks. I was responsible for many old windup alarm clock's death. I'm never satisfied with just having something as I have a bit of a drive to know how things work. It's been confined to electronics mostly down to individual transistors and logic gates which is why I work with embedded systems.

I'm here because I have a fascination with mechanical watches. I own two, a Seiko 5, and a Maratac GPT-2. The GPT-2 has a Miyota 9015 movement and is mostly well behaved though I'd like to get the +10 sec/day down to at least half that.  The Seiko 5 is a bit of a mess. I bought a new one to act as a daily beater and used a phone app with a microphone to get a basic look at it. It's at a bit over -22 sec/day and has a 3ms beat error. My initial goal is to be able to regulate my own watches then to be able to service or repair them.

Welcome,

I have a very similar background story to you except skimmers (DDG's mostly). I still do reserve days when I don't have my contractor hat on.

Hello Spook and Welcome to the Forum.

There are some good videos by Mark on correcting beat errors and regulating your watch and lots of postings to trace through.  I am sure that if in a spot of bother you will get help here, at least parts for a Seiko 5 are quite available so you can get stuck in there.

Cheers,

Vic

    • Hi. It’s either riveting or welding . I have seen some small home made welding tools on UTube at times may be I should have a go at building one, they are small spot welding machines. Suitable for the likes of these type jobs.
    • Hello and welcome from Leeds, England. 
    • Hi watchweasol, yes that is a way of doing it I suppose, I have a pair of mainspring hole making pliers on their way off eBay, the ones with the different shaped punches. I may be able to use them to make a hook.
    • Hello everyone, Glad to be here. 
    • This is a modern watch, the crown is definitely made from solid 316l steel. You must have heated the crown to some 200C caused the surface colour to change to light yellow. It's similiar to steel tempering. Yes it is the chromium oxide that forms during the heating that gives rise to the colours you see as you know stainless steel contains chromium. The fact the crown is SS lead me to a question, you've never heard of the alum method? Because alum would work perfectly in this case, instead of drilling, which, there is always a risk of damaging the crown, I would just let the crown chilling in some warm alum solution for 1-2 days and the job is done.   Sure can but the thing is the crown is not just mirror finishing, the lock symbol is polish while its background is some sand-blasted finishing so it would be hard to replicate that. You can buff it all shiny but losing the sand-blasted finishing means it won't look exactly like before.   Gasket is always tricky to me. I would try to use some gasket that look closest to the broken one in term of thickness and diameter, and check if the replacement gasket fit with some friction to the case tube. Lastly you can still use alum at this point.
