Type B

Serial Number Ranges: 875xxx-876xxx, 1004xxx-114xxxx

Notes: The Type B dial is a dial iteration with many subtypes. While the Type A “Swiss Only” can be seen with underlines, the Type B is frequently seen with an underline, extra ‘swiss’ marking, or combinations of both. Every subtype of this dial is rare and they represent an interesting transition period.

The best way to distinguish the Type B’s coronet and basic text, vis-a-vis the other non-chapter ring dials, is through its tall and stringy coronet. Of any other dial iteration, it looks closest to the Mark I matte dial. The further idiosyncrasies to the Type B include the following. The ‘Rolex’ font is identified by the right-angled serifs on the ‘L’ and ‘E’ as compared to the 60 degree slopes on the Types A and C. The ‘oyster perpetual’ and SCOC text are unique as well (which can be seen best in the ‘longer’ middle E bars). Lastly, the ‘swiss’ font is moved down to the very bottom of the dial as compared to the Type B “Swiss Only” dial.

These dials exist in four main flavors:

  1. Underline single Swiss
  2. Non-underline double Swiss (Swiss T<25/Swiss)
  3. Underline double Swiss (Swiss/Swiss)
  4. Non-underline single Swiss

I have not yet seen a non-underline double Swiss (Swiss/Swiss) or an underline double Swiss (Swiss T<25/Swiss). Additionally, within all of the marking variations, there are some seen with ‘radial’ lume plots that are set more centrally. There are even a few “Triple Swiss” dials out there – confusing, I know. See the pictures below for a better idea. Also, Edmond Saran of Le Monde Edmond has put together an excellent article on the double swiss here. His site is one of my favorites and I encourage you to look through it when you have time.

These Type B dials clock in close to the end of the pointed crown guard era but should only come in PCG / ‘Cornino’ cases.
