I know everyone's seen this before but it's worthy of mention because of the simple and elegent way in which the complications are provided. Spectacular movement too...

That's because 1 comes after 31 ;) the other dots represent days, there is no day between 1 and 31 yet they want to show both 1 and 31 as they are significant and they're odd number.
I have seen a PC which has a 31 and the shorter 1 next to it which is more aesthetically pleasing but cannot remember which.
I reckon this is going to be a short thread!
Some real beautiful pieces. I will need to dig mine out from the safe and post some pictures.
That watch looks great Jacob.
Here's mine
Wow, what a good thread.

This should have been started in the Bullingdon Club
G and T with frozen water and fruit anyone
Superb watches guys.Slightly different league than anything in my collection. Great to see here.
Damn! Does this mean I have to get one if I want to join in?
Loving ALL the JLCs....
Indeed Neil But it has taken 7 years to develop that WIS restraint, had this happened earlier on in my wisdom in my mid twenties, I would have been so irked and upset I would have driven to the JLC workshop in Camden and begged them to fix it there and then. We live and learn and grown up eventually, I was frustrated but it teaches you something in the process ;)

... well, the GST PC is not a small watch by any means and when it was introduced 13 years ago it was considered as very large and heavy. However, by today's standards it is pretty much a "regular" size, i.e. way smaller than a 45.5mm PO (or the PO Chrono) or any normal Panerai. And the diameter (43mm) is no problem on a normal sized wrist - but you have to wear this watch rather tight because on a loose bracelet it tends to feel top-heavy and wander around or the crown ends up in the back of your hand.
But if you manage to adjust the bracelet to a good fit, the watch sits nicely on the wrist and you get used to the weight quickly:
And, as mentioned before, with regard to value for money they are pretty unique for a perpetual calendar.

The two JLCs are absolutely exquisite.
What is this porn page ?? :drooling:
sorry to be a idiot, but i always get confused by this
annual calendar shows month as well as date, but doesn't know how many days are in each month, hence you have to manually adjust at the end of a month without 31 days?
Perpetual calendar adjusts for the number of days in each month but doesn't need adjusting, except during leap years?
what are the IWC versions that even know the year and don;t need adjusting even with the leap year?
Annual calendar knows each month but thinks February has twenty nine days so needs adjusting once a year for three years out of four.
Perpetual calendar knows the leap years too so never needs to have the date adjusted.
Hope this helps.
When I say it "knows", obviously I know that it's mechanical and can't know anything. it's just easier to describe than by going into the complexities of the mechanics of the movements.

... a perpetual calendar does not need any correction for regular leap years (only every 100 years, because every 25th leap year is skipped in our calendar), no matter whether the watch shows the actual year (as with IWC and some JLC) or has a leap year indicator (Patek, ALS etc.).
An annual calendar requires one correction every year at the end of February - for every other month this complication "knows" the correct number of days, i.e. it switches correctly after either 30 or 31 days. Typical examples are the Patek annual calendars or the Omega Aqua Terra Annual Calendar.
A full calendar shows day and month (often moon phase as well) but requires adjustment at the end of each month with less than 31 days. Typical examples are the JLC Triple Date or the Zenith Chronomaster.

addendum: Annual calendars usullay have only a month length indicator disk with two steps - 30 or 31 days; I don't think I have seen one with a 29 days indication for February.

I believe even perpetual calendar ones need adjusting twice a month too because of the change between GMT and BST.
