Nautilus ref. 3700 - How to n.10 - Dial types - definitive
Hi friends,
"How to" number 10 is about the most difficult, hard studied research I've ever made: the dials of the Nautilus ref. 3700. Many and many years of study, hundreds and hundreds of pics thoroughly analyzed, hours and hours of interviews with collectors.
Here it is for you. (also available on issuu . com / mstanga )
HOW TO n. 10 – (The dials dilemma part. 2 - the Patek Philippe Genève writing – dial types)
I've been studying Nautilus ref. 3700 for so many years but what happened to the dials is still a dilemma with many certainties and some assumptions.
All of this that will follow is based only on my multi years studies and respects only my personal opinions, can not be considered the absolute truth that is the prerogative of Patek Philippe itself.
Dials were created and made "usually" by Stern Frères, generally hand made and the stripes engraving techniques differed with years.
In this "How To" we will focus on the writing "Patek Philippe Genève and on its correlations with what is written at 6 hours.
We will start taking as an example the image on the Patek Philippe booklet that was sold together with the watch starting from 1976 and from there we will continue analyzing all the possible known variants, so will face dial type 1(lines) and 1B(dots), 2, 3, 3, 4, 5, 6, 7, and the after service dials.
If I were to advise someone (that want to be sure at 100%) on a purchase I would say that it is better (almost mandatory) to choose, in addition to other checks, one 3700 with type 1 (lines or dots), 2 or 3 dials. (Dials type 6 and 7 are to be placed temporarily in a precise way and very carefully.
Type 1 dial
The very first ref. 3700/001 starting from 1976 until movement serial number lower than (about) 1303999 and case serial number lower than (about) 533000 had the minute track with little lines and not with dots as we are used to see in the most of 3700's dials. We find at 6 hours "sigma SWISS sigma" and the stress is very close (attached) to the second "E" of GENÈVE, the "H" is narrow, the legs of "K" are converging (to the same point). We can find this kind of writing on the dials with the minute track with dots too (type 1B (dots).
Type 2 dial
This type of writing is similar to the type 1 (maybe the writing is a bit thicker), the stress is very close (attached) to the second "E" of GENÈVE, the legs of "K" are converging (to the same point) but the lower summit of the "V" is truncated, "H" is a bit wider, the upper semicircles of the "P" are a bit different. We find at 6 hours "sigma SWISS sigma" This type of dial was mounted starting from about end of 1977 beginning of 1978.
Type 3 dial
This type of writing is similar to the type 1 but the lower summit of the "V" is truncated, "H" is a bit wider, the stress on the second "E" of GENEVE is not so close, still attached but a little more prominent and the legs of "K" are not exactly converging to the same point. We find at 6 hours "sigma SWISS sigma". It is supposed that this type of dial was mounted starting from about end of 1978 beginning of 1979
Type 4 dial
The main characteristic of this dial is that we do not find the stress above the second "E" of GENEVE, the "H" is wider than in type 1, 2 and 3 dial, the middle line of all the "E" is about as long as the upper and the lower one. We find at 6 hours "sigma SWISS sigma". My opinion is to pay close attention in evaluating for a possible purchase a 3700 with such a kind of dial because we have evidence that Patek Philippe used since the 80s this kind of dials as replacement (it was common practice, on the occasion of a revision, replacing the dial, without cost to the customer, if this had been considered damaged)
Type 5 dial
Almost the same characteristics of the type 4 dial but the form of the "K" is very strange with the lower leg very much shorter than the upper one, they are converging to the differents points, the "E" are wider and the middle line is very much shorter than the upper and the lower one. We find at 6 hours "sigma SWISS sigma". My opinion is to pay close attention in evaluating, for a possible purchase, a 3700 with such a kind of dial
Type 6 dial
Starting from about 1980 we began to see also dial with "? . (dot) SWISS . (dot) ? "(type 6) and ". (dot) ? SWISS ? . (dot)" (type 7), these two types of dials have common characteristics except for the writing at 6 hours. The minutes track's dots (6, 7, 8, 9 – 21, 22, 23, 24 – 36, 37, 38, 39 – 51, 52, 53, 54) are extremely external to the minutes track itself, the writing "PATEK PHILIPPE GENEVE" is higher, the legs of "K" are not exactly converging to the same point, the stress is detached from the second "E" of GENEVE, sometimes these dials are of special colors (very light blue or even green).
These dials are to be placed temporarily in a precise way and very carefully.
Type 7 dial
Starting from about 1980 we began to see also dial with "? . (dot) SWISS . (dot) ? " (type 6) and ". (dot) ? SWISS ? . (dot) " (type 7), these two types of dials have common characteristics except for the wrinting at 6 hours. The minute track's dots (6, 7, 8, 9 – 21, 22, 23, 24 – 36, 37, 38, 39 – 51, 52, 53, 54) are extremely external to the minute track itself, the writing "PATEK PHILIPPE GENEVE" is higher, the legs of "K" are not exactly converging to the same point, the stress is detached from the second "E" of GENEVE, sometimes these dials are of special colors (very light blue or even green).
These dials are to be placed temporarily in a precise way and very carefully.
After service dials
It is our opinion that dials with only "SWISS" at 6 hours and without the stress above the second "E" of GENEVE are "to be considered after sevice dials mounted by Patek Philippe in a second time
About the following dial we have written documentation of a replacement made by Patek Philippe during a service because the dial was damaged
