3186 would indicate as much. There's the 'wiggle test' to check. All 3186s have the blue hairspring to my knowledge.

The parachrom hairspring was first introduced in the Daytona with the inhouse cal 4130 way back in 2000 but back then it was more of a grey colour. So if this parachrom hairspring was so wonderful why did it take many years to introduce it to the complete Rolex range. Simple answer cost to tool up, as they were using the nivourax hairsprings made by the swatch group then.But when they stated they would no longer supply parts outside the group Rolex was forced to finally make in vast production there own hairsprings. Your watch will have a parachrom hairspring but no big deal, as for a parachrom hairspring well that's just a hairspring.And like all hairsprings perform basically the same and in the real world would doubt if you would find any real benefit no matter the hairspring in the case. As long as any watch is regulated correctly it will be as accurate no matter the hairspring afraid there is nothing magical in a parachrom except now its made in house and a very very very tiny bit less magnetic.

3130 base without date, now some later models reported with parachrom.
3131 parachrom
3132 parachrom and paraflex shock system
3135 base with date
3135 Subc parachrom
3136 parachrom bleu and paraflex shock system
3155 base with date & day
3156 parachrom bleu and paraflex shock system
3185 base with date and GMT function
3186 parachrom bleu
3187 parachrom and paraflex shock system
4130 Chronograph Parachrom started 2000 but then a more grey colour now parachrom bleu which is done by some chemical prosses to turn it blue
4160 parachrom.
9001 parachrom.

The wiggle test have nothing to do with the hairspring with the cal 3185 for one full crown turn time zone hand would jump around 5 hours on the 3186 around 8 hours.

Thanks Padi, as all we know that they're enlarge all their so-called advantages for the commercial purpose, it's not difficult to find it out from infant milk to gasoline.

I know. It's a good way to check for a 3186 though in these late models. And with the 3186 comes the blue spring the OP's after.

And today many pay extra for the 3186 god knows why, expect because the internet dictates them as so called rare. I would rather have a 3185 any day over the 3186 as it had quite a few faults that the 3185 never had.Same for the so called mistake or stick dial GMTs on the net they were stated as having a 3186 inside. And many paid the high prices that dealers were charging for 3186 watches only to find that many of these dials still had a 3185 inside.

What were the differences or faults between the -85 and -86 movements?

Early 3186 had date change problems but rectified later by Rolex main difference was the detent gear in the 3186.That gave slightly better second time zone settings for one full crown turn 3185 second time zone jumped around 5 hours while 3186 jumped around 8 and that's it but myself would still take a 3185.

Peter, I’m interested … can you please expand on this, I’m not quite following.

It was the spring on the date slide cam caused the date to stick Rolex rectified and fitted many warranty claims with a stronger spring.But it's no better or more accurate than the 3185 so myself would choose a 3185 over the 3186, there are a few very minor differences in the 3186 over the 3185,but many parts are interchangeable.

Thats pretty much totally incorrect, date function is exactly the same as on 3135. They didnt change that spring.

It was a redesign of the spring on the intermediary GMT wheel that could snap in two.
I too prefer the 3185 though, a nicer design. There are quite a few parts that differ though including both top movement bridges.

If you send a rusted up 3185 for movement exchange today, you will get a 3186 back from rolex, as they no longer manufacture complete 3185s. So overpaying for a 3186 is kind of foolish tbh.

Thanks Padi.

At one Rolex had a video with the case back off,with a big magnet dangling close to the hairspring.What this means in the real world,if you don't wear your watch with case back off with a magnet dangling over the movement .Then again in the real it's doubtful if anyone would notice any difference no matter the name or make of hairspring in the case.

Huh, that article just proves what I said, but it doesnt even show the new design of the click spring, which has nothing to do with the date.

Ive serviced 100s of these :) I know a ton more about it than "Peter"
