Universal Geneve “Nina Rindt” Dial

My research is focused on the “Nina Rindt” (primarily the Universal Geneve 885103/02, though I will touch upon the Pulsations reference in the Bezel section), as opposed to the 885103/01 “Evil Nina”, which is identified by its black dial and white registers.

The Nina (885103/02) was manufactured with two different dials, with the most noticeable difference being the Universal Geneve logo, which is either applied or printed.

The two dials found on the Universal Geneve 885103/02

Both dials are primarily white, with any print in black, including dial text (UNIVERSAL GENEVE, COMPAX, SWISS T (and 25 if applicable), and hour/minute/second and 1/5 second marks.

The registers are black with white numerals and marks. The running seconds has numerals (no marks) at 20, 40 and 60, and equal length marks each of the other 5 second increments. The 30-minute register has numerals (no marks) at 10, 20 and 30, with marks at the other minutes, primarily shorter marks, with a slightly longer mark at 5, and the longest marks at 3, 6 and 9 minutes. The 12-hour register has numerals (no marks) at 3, 6, 9 and 12, with marks of equal length for all other hours.

Both dials have the same luminous on the dial, which are at the outside end of most hour marks (1, 2, 4, 5, 7, 8, 10, 11) as a square. At 3, 6 and 9 the luminous is rectangular, replacing an hour mark. At 12 there are two square lume plots, side by side above and centered horizontally over the hour mark.

Differences in early and late dials:

Early dial: seen up to 2.4 serials
The first dial has an applied silver Universal Geneve logo. This raised reflective logo dial is known best to the community as the “Mark 1” version of the Nina. This dial pairs with specific set of main hands, detailed in the Main Hands section. These dials are marked “SWISS T” below the 6 o’clock index mark.

Later dial: seen from 2.5 serials and on
This dial, known as the “Mark 2”, has a printed black logo, with a “U” within a box. Per Universal Geneve, the manufacture made the switch from applied to printed logo on dial in 1971 [1] – actually I found it somewhat curious they would even provide this date, but not provide information on date of changes in register hand design or crown logo. This dial pairs with a different set of main hands (see Main Hands section for details). These Mk 2 dials are marked “SWISS T 25” below the 6 o’clock index mark.

There is one later ‘printed logo’ dial seen with a 2.4 serial on the caseback. This may have happened during the transition period, though I would be interested in seeing more later dials with 2.4 serial numbers before claiming this as correct.

Some claim that the 2.569 serials are more likely to develop tropical dials. While I have seen a few in the 2.569 range that are tropical, with such a low number it is difficult for me to say that I believe that range is more likely than 2.4 to be tropical, as we see a number on that batch as well.
