Enjoyed this one very much. I am hoping to get a blue dial Orient Bambino to wear for my wedding. I've always loved that watch. I'll have to refer to this article to explain the "but why mechanical.." question.

Wow very comprehensive & well done. If mechanical watches tickle your fancy, there is a ton of watch repair video on YT. I particularly enjoy wristwatch revival ( https://www.youtube.com/channel/UCD80T1s2Za4K682CQDGwEKQ ). A warning though, if you consider to get into that hobby. I tried, it's really hard, expensive (I spend close to €1k and that is with b-quality stuff. Good stuff is 5-10x more expensive.) and can b…

If you wouldn’t mind answering a question, how difficult is it to swap a dial/handset/movement set into a different case? I saw a custom mod watch that paired the face/movement of a Marathon navigator with an O&W diver case*. Is a combination I find desirable (as the Marathon bezel is too chunky for my use), but the maker won’t respond to emails. Is it possible that the combination could be “ drop in” or is it likely…

That really depends on the sizes, if the face and movement are the same size I expect it should be easy enough. You will need some tools and fine motor skill, but no where near as much as you need when taking apart a movement.

Looking at the two watches you mention, the navigator has a Quartz Harley Ronda 373 movement and the diver has a ETA 2824-2 movement. The 373 I can't find the specs for, but from an ebay auction it seems to be a 11½’’’ diameter. The 2824-2 is the same diameter. However, all 11½’’’ ronda quartz movements I can find are 3mm thick where the 2824 is 4.6mm. So what I'd expect is that it will fit, but you might not be able to secure it properly. It really depends on how the movement is held in place. Perhaps you can fabricate/3d-print a spacer for that.

Another consideration is the lug stem, that might not be the right size. To long is solveable, to short means buying a replacement. I am also not sure wether the stems can have a different thickness, to thin and it wont be waterproof, to thick just won't fit.

You could probably try without destroying anything (no guarantees ;)), you are not really touching any of the fragile & tiny parts. But you will atleast need tool(s) to open the cases, they might be different, and a tiny screwdriver to release the lug. And I wouldn't count on it remaining waterproof, not sure.

An SKX isn't gonna outlive you and once it fails they'll just replace the entire movement anyway. Mechanical watches are still indeed cool though. :)

As an owner of an SKX who doesn’t know much about watch longevity, how long can I expect it to last? Are there other automatics that will outlast a person’s life? It still blows my mind that you can take the SKX scuba diving, especially when you factor in the price. This may sound cynical but as I get older and see the world becoming more and more digital and connected, I find myself appreciating analog, mechanical t…

> Are there other automatics that will outlast a person’s life?

Very unlikely. You do hear the occasional story of a mechanical watch running fine for several decades without requiring any servicing, but there's a lot of survivorship bias at play there. It's extremely unlikely to go ~8 decades without needing servicing. Keep in mind there are lubricants at various places in the movement that are essential to proper operation that evaporate/denature over time.

I have an automatic mechanical watch - a Seiko 5. It loses about 5 minutes a day. It might only need an adjustment to calibrate it, but that would require a watchmaker. I think the last one in town just went out of business, and even if he hadn't, the cost of his labor would be greater than the cost of the watch.

It's not hard to make the adjustment, but you need a timegrapher to measure the results in a reasonable time. I've adjusted a couple of my watches over the course of a week or two by making small adjustments, noting the time, wearing it for a day, and then noting how much the time had changed versus a "known good" time. It's a pain but doable. There are mobile apps that use the phone's microphone to measure the watch…

> but you need a timegrapher to measure the results in a reasonable time.

This is just an app now. All a timegrapher is is a microphone and software, and, well, your phone has all that. This is the app I use; I highly recommend it: https://play.google.com/store/apps/details?id=com.watchaccur...

This may not be the most valuable comment, but my goodness, the quality of this writeup and it's interactive descriptions of complex mechanical components AND their interactions is radically impressive. The treatment of complex topics in deeply visual and partially interactive ways, for me at least, is a remarkably helpful way to learn.

This might be the single best work of art on the Web I've seen since 1995. Nothing else even comes close.

i'm continuously astounded by how accurate the Omega Aqua Terra is. it will be within 90s over a 30 day period after 4 years of daily use with no servicing. the fact that something mechanical and so tiny operating at 3.5hz can do this is mind blowing to me. it has a cool [8800] co-axial escapement: https://www.kapoorwatch.com/blogs/through-the-scope-the-omeg...

If you want absurd accuracy in a watch powered by mechanical energy (without just resorting to a battery-powered quartz), look into Grand Seiko's spring drive. It's super interesting technology, and the result is a smoothly sweeping second hand (as in it's actually continuous, not merely a higher number of beats per second).

He does it "the right way™". Use the platform. Don't use any framework or generic library. Go straight to the point and code what you need, when you need it. Don't minify or bundle anything, and let the people who are learning and courious a straightforward way to connect the dots, without forcing them into a github repository with 90% of the code unrelated to the thing and existing just to glue 1000 pieces written b…

We need a ciechanow.ski explainer for how ciechanow.sky explainers are built

Where are the comments in his code? :-)

Thank you for the detailed response! It’s the sort of project I find intriguing, so I’ll have to do a little more digging. May end up being beyond me though.

Edit: I see that Marathon does make several watches with the 2824 (which would presumably simplify the process).

Depends. The ETA-2824 is a fairly common movement with inexpensive Chinese clones, so dials and hands are reasonably cheap and common. If the target case also uses the same ETA movement then it’s simple: Unscrew the back, remove the crown stem, drop the movement. Assembly is the reverse of removal. Where it gets tricky is if the target doesn’t use the same movement. In that case, I’d just buy an AliExpress watch with…

Thanks for the response!

There's something magical about mechanical watches. Maybe it's just knowing that you have this perpetually winding machine on your hand (in the case of "automatic" mechanical watches). Also knowing that the thing will last forever, take care of it and it will probably outlive you. Can't say that about an Apple Watch. If you want a good mechanical watch that won't break the bank I suggest picking up a Seiko SKX (thoug…

A mechanical watch needs regular service which is usually just cleaning, lubricating, replacing seals and springs. Eventually it will need replacement parts and that is probably the end of life for the watch. There are a some brands that will service every watch they've ever made, fabricating new parts as needed. Few of us can afford one of those.

My grandma has a mechanical watch she only wears on sundays - to the church. Whenever I was visiting her she asks me to wind it up for her before the mass. She uses this same watch for over 30 years with minimal maintenance, and it's not an expansive brand, just a good noname watch.
