IWC Porsche Design MechaQuartz Chronograph Moonphase Ti

Apr 27, 2016,15:42 PM

This afternoon I'd like to profile a watch I really like, that I hardly ever wear, photographed with a camera (iPad) I've never used before, without leaving the comfort of my recliner chair.

The watch is thin. It's light.

It's grey and blue and gold, with a bright red Chrono hand. The pushers are integrated into the case design, as is the bracelet/lug transition. The crown screws down. The bracelet has an integrated push-button clasp. Of course, it's Swiss made, but Porsche Design gets a subtle credit in the buckle and in the moon subdial.

The finishes are matt and polished titanium, with a very glossy dark blue bezel and a soft medium blue dial, highlighted by shiny gold rings around each subdial, gold hands and gold markers.

Even the date window at 4:30 shows careful design consideration, with a matching blue ring with gold letters.

The MechaQuartz JLC-based 630 movement is a hybrid 25-jewel assembly, with a quartz timekeeping 'engine' and a mechanical 'snap-action' chronograph. It has two cousin movements: Cal. 631 comes without moon phase display, and Cal. 633 has an alarm. They were used in PD watches too. Always covered by a case back, so there was little finishing.

A factory picture

These movements incorporate two separate quartz-controlled stepper motors, one for the 'watch' (1 Hz, 3600 bph) and one for the chronograph (4 Hz, 14400 bph). Strangely, the chronograph still runs when the timekeeping portion is stopped by pulling out the crown fully! I guess you have to trust me on this, but observe:

As you can see in this side profile, the links are connected by pins. The watch came with an IWC pusher tool so the owner can conveniently adjust the bracelet at home (without getting up from his chair). It looks like a few of those pins need some minor pushing.

I hope you enjoyed this armchair review. No calories were expended but my battery is down to 5%. Thank you for reading.

This is the gallery of beauty photos which the seller used to entice me into buying this watch, back in June of 2003. (I had to get up to plug in my iPad anyway) ...

Your post takes me back to my early acquisition days, when Porsche Design watches were my favorites and I had a dozen at a time. Until seeing your post, I'd forgotten that I owned this very model. Porsche Design's collaboration with IWC produced their mos...  

Your collection never fails to surprise!

I recently acquired this piece in none working order, super unfortunately. Any idea of where to send to fix or at least get time going don’t really need the chronograph to work.

They’re great..

The alarm also can be seen on the reiseuhr (world time).. which came in two dial flavours and a couple of strap options. I think from asking the Iwc service pages they will still touch these.. al ...
