Differences between 3712 and 5712

Back to the topic... I could not find the material I got from Patek in Geneva. The enclosed pictures I took from a relatively new book Collecting Nautilus and Modern Patek Philippe Wristwatches" by Osvaldo & Patrizzi. I can recommend the book to the interested ones even it's costing as much as the service of a Calatrava.

Anyhow, I have many times emphasized that 3712 is having a case made of two parts. This is the original design of Mr. Gerald Genta. Here is the drawing of the case. It looks very simple but it is not cheap to produce.





In the case of 5712 there are much more parts. It is cheaper to construct and it is much closer to the traditional case construction than Genta's original design. The construction looks as follows:





Next the watches side-by-side. The older model 3712 is on the left and 5712 on the right. If you watch the picture carefully, you will start to see the differences:





The main differences listed:

Case at 3 and 9 o'clock                                                           straight                                                                                         shaped
Direction of the date numbers                                                same as reading direction                                                       partly upside down
7 o'clock marker                                                                        present                                                                                        missing
6 o'clock marker                                                                        rectangular                                                                                 rounded off
hands                                                                                          heavier                                                                                        slimmer
center links of bracelet                                                            more rounded                                                                             more square

I had an opportunity to compare my 3712 with a new 5712 and the feeling of the bracelet of 3712 was more sophisticated and comfortable. But that is just a matter of taste.

The two watches share the same movement and they look very similar. But thanks to the case construction, for me they are two different watches.

Best, Kari

Overall I prefer the 3712,

maybe due to its rarity (though that seems to make little sense). You have however missed 2 details which I find preferable on the 5712. First the font on the date wheel is larger, therefore easier to read. Second, the crown is larger on the 5712. The sma... 

Thank you for your comments,

I did not even try to make a complete list. There are also some small differences on the seconds sub-dial, power reserve dial, the hour markers are also a little bit different, etc. I don't care which version is rare and which one not. The rarity can only... 

Great comparo Kari! Thanks for this.

The devil is indeed in the detail. I start to see why you love your 3712.
