5001 vs 5007 differences?

Just wondering what changed between the 5001 and 5007?

Hi,

Quite important changes:
1. cosmetic: curved springbars/strap, convex sapphire glass at the front
2. movement: completely newly developped 52000 series. Check the picture I took at SIHH or you can find more at IWC's site

I have the 'old' 5001, the new 5007 has visually only subtle changes and mechanically very important ones.

thanks that extremely helpful so i should hold out for a 5007 vs a 5001 then

That's a matter of personal preference I guess.

It's a matter of preference, as Bob suggests - but I think there are so many improvements in the latest movement. The Black ceramic winding pawls on the Pellaton winding system are dramatically better, and nearly eliminate material loss/degradation and can extend the service interval and winding efficiency.

Also, the new rotor and those blued-screws are nice to look at...

Agree R., did you notice that the A R D O I S E version is no longer there...

Best,

B.

thanks guys a 5007 or 5001 will certainly be my next IWC - i had been looking at this for years now I've finally sorted the BP out the Portuguese is next on my hit list.

The blue screws and full gold rotor is only limited to the Perpetual Calendar models. I believe the standard 5007 has a standard finish.

The new caliber is of course, a significant improvement over the last one. However, I find that the older caliber with its single barrel and additional mechanism to stop the watch from being inaccurate when the power reserve is low, is interesting and unique to IWC. I find this complexity attractive and intriguing. It has its charm.

I think it'll be a tough choice to choose between the 5001 and 5007.

Hi Alex,
A good question and one I looked into with interest as I too was confronted with the same thought ... current model or wait for the latest.
So I went to work and came up with this.
The 5007 operates at 28,800 VPH ( 5001 at 21,600 VPH )
Twin barrel winding ( 5001 single barrel )
Rotor bearing, pawls and auto winding made of ceramic on the new movement with
slimmer rotor with smaller gold medallion.
The 5007 has 31 jewels , the 5001 has 42 jewels, which I found surprising.
The case height on the 5007 is 14.5mm as apposed to the 5001 at 14.0 mm.
New curved leather strap tailored to fit the case on the 5007, as apposed to the straight finish on the 5001.
The new watch will be more expensive as a result of these new improvements of course but also more so due to the Euro parting ways with the Swiss franc.
By the way .... if anybody else has noted any other changes, please feel free to add to my findings.
I ended up buying the current 500114, I guess because I got a great deal on the watch with immediate delivery plus, plus, despite the fact that there were numerous improvements on the new model, I was just as happy with the current model, for some unknown obscure reason.
Cheers and good luck with the purchasing decision.
Neil.

thanks again guys....very interesting, i wonder if the 2016 BPP will have similar changes to the movement which will be a little annoying given i just bought a BP 5009

Tried on the 5007 today. After the BP arrives it will be next. The panerai 233 will have to wait

Exterior of the watch is the same apart of the strap attachment. However, as Neil already mentioned the movement is remastered. Apart of improvements to winding system, which should make it more robust, it also has twin barrel winding system to enable movement to operate at 28800 VPH rather than 21600 VHP previously. Which in theory should further improve the accuracy.

In my humble opinion, the old and the new are both just as good. Running at a higher frequency is more accurate but also wears out the watch faster which is why they used ceramics and what nots to counter those effects.

Further to that, a twin barrel power reserve has marginal benefits given that this is typically a dress watch, a board room watch or a weekend away at the winery watch. I have a twin barrel Reverso Grand GMT with 8 days of power reserve but I only use it for 3 to 4 days max. I have yet to see my friends wearing their IW5001 all day, everyday, all season and all terrain. For me, I have my Fliegers and Aquatimers to accompany me for trivial day to day activities.

Again in my humble opinion, whilst these new introductions are technically sound, I can't help but look at the new model and feel that they have just tried to do 'too' much to it. Everything from the engravings on the clasp to the leather band and to the shinier bits and pieces to the more colourful assembly of the movement with blue screws and etc. It's just getting a little bit to 'out there', too 'showy'.

I am a sophisticatedly simple guy who appreciates understated elegant form and function. As such, I still prefer the classic and subtle beauty of the Portuguese 5001. For me, it has the right balance of curves, sharpness, shine matt finishes, including a perfect balance on colour, tones and presence.

This of course is just my opinion.

Taking advantage of the topic, I wanted to ask if anyone knows if the improvements in the 52000 movement will make the 5007 more suitable to be put on a winder than the 5001. I remember reading in the forums that IWC itself did not recommend using the 5001 on a winder in order to avoid excessive wear on the movement, but I wonder if the new winding system and ceramic parts would make it ok for the 5007. Thanks!

When you have your watch serviced, worn parts are replaced so I wouldn't worry about keeping either one on a winder. Moreover, replacement parts have also been upgraded and newer materials (such as ceramic) utilized, further improving wear-resistance. I had not heard of any recommendation on winder use.

Does the new movement have the function of stopping the watch when the springs are nearly unwound (at the end of 7 days) or has the power reserve been shortened in comparison to the old movment that had more than 8 days of actual autonomy?
