Linde Werdelin Land Instrument II - The Rock
Computer technology, unlike wrist watch technology, has no choice but to be upgraded continuously. So here is the upgraded Land Instrument from Linde Werdelin. What is it you may ask (for those uninitiated)? In a nutshell, it is a sensor-based device that gives you lots of important information using data collected from an internal compass, barometer, altimeter, inclination meter, and separate (but wirelessly connected thermometer). It also has an optional wireless heart rate monitor that straps around your chest. Using all this information in conjunction with the native ability to process it and store it - gives you an instrument, the Land Instrument II to be exact (now called "The Rock"). Along with that, there are basic functions including alarms, stopwatches, the time, and lots of logging capabilities. The Rock now also features that ability to connect with a GPS device. For a good idea of the functions of a Linde Werdelin Land Instrument, read my review here.Technical Specificatio

2009 Time Zone Ladies Watch of Patek Philippe has a traditional CH
The Watch has a traditional CH of column-wheel-controlled 29-535 PS caliber hand wound movement and patented improvements to make the watch really reliable. The buttons on the side can be used to enable/disable the chronograph functions and a fluted Crown contributes to hand-wind of the movement.

Noob Question.. Do you dive with your OP is position 1?
I feel like this thing should screw down tight no?I read the book it SEEMS to say you dive with it in position 1.....I can push the crown down against the watch, but screwing lightly has no effect (that's' what she said) for it staying in (What she said again lol)

Nautilus too big?
I am on the search for a Patek, either a Nautilus or an Aquanaut.I'm considering the 5712, 5726, or the 5990 from the Nautilus range, and the 5164 from the Aquanaut range.I have small wrists (6.5) and although I am ok wearing a big watch when 'big' suits it (I.e. An AP Diver) I'm not keen on watches that are designed to 'wear normally' looking too big for a wrist.Having looked at lots of pictures, the 5726 seems to wear quite big, bigger than the 5712, although this also seems to wear bigger than the Aquanaut.The 5990 is a little different as it looks like it's designed to wear bigger and looks a bit more rugged by design, although I could be wrong.I hope I've made sense, but given that I may have to buy blind due to limited availability to try on, if any of you guys have a view, it would be most appreciated.Sent from my iPhone using Tapatalk

5164A-001 availability versus 5167A-001
So I am on waiting list(s) for the 5167A-001. I have not been given any indication of how long it would take. I just know I am number 11 on one waiitng list at an AD.While calling various ADs in Switzerland to check availability, I was told that waiting time for the 5164A-001 is only 3 months. So now I am questionning myslef on upgrading or not although budegt is not the same. Is the 5164A-001 taht easy to get from an AD?I would prefer to buy my first PP from an AD to at least get my name on the watch certificate. From grey, 5167 can be available within 1 months with a 8% premium.
