The Mil Sub got fixed pins BUT it also was used only with a nato or zulu strap not bracelets. This was for safty as well as security.
With a Nato or zulu strap you are free to loose at least one spring bar and the watch will remain attached to your wrist too so that makes the Nato/Zulu a good security device in any case.
From a safty standpoint the watch really needs to be able to seperate from your wrist in at least two places, with springbars that means the watch head and the clasp, if you catch your watch on a sail for example or in machinery it is far better for your watch to come off than for you to get tossed in the sea or get wrapped around a piece of billet spinning at 5000 rpm...
Fortis has the best system for screw pins I have seen, no threads in the watch head and a keyed pin with a screw.
double screw systems as you pointed out are difficult to manage.
The reason I don't like screws is that they pose a long term service problem, only smaller watch companies use them and that means 10 years from now they simply won't be available when you strip a thread or loose a screw so you will be converting to springbars or not wearing the watch anymore.
I understand and know the point with the nato strap: But those watches with screw-bars are not made to be used only on nato straps and when used on bracelets/leather straps, screw-bars hold better.
But springbars become a weak point: Just one who loose on the bracelet and the watch is off as you know.
I work myself in the oil industry and know very well the problem with machinery but the rule number one if you work very close to spinning machinery is: No rings, no bracelets, no necklace of any kind, no watch and so on.
Still, I saw some guys getting the gloves or sleeves tooken into machines and beeing wounded: A twisted sleeve of working cloths can lift a man's weight, so you are allways in danger if too close to spinning machinery.
A bracelet who whould break anyway at a pulling-point of maybe 25-30kg , the springbars would loose earlyer.
Security is important but we can't sail naked for that, so in those situations, we have to make a choice anyway: Actualy, the best in my meaning is to wear tight thin gloves who comes over the watch to avoid hookings like that.
I agree that the screws are not a random product who's made on large scales in all forms(except for Pams: Look on the net, those screws can be bought by hundreds...)
But it's like everything else: Who garantie us 100% that Ball will be there in 25 years to replace them luminous tubes? The quartz revolution is the typical exemple of unplaned downfalls who killed many brands and made parts difficult to get...
Parts stocks never last forever and anyway there's a bunch of bad springbars on the market: It's actualy not easy to get top aftermarket quality who fit perfectly the holes in your lugs.
We just have to live with that and try to hold carefully on the screws/parts anyway...
I got nothing against springbars and don't call them "idiots" as they serve what we take them for: I just got my meaning on them...
