Serial Number Range: 875xxx – 172xxxx*
General Notes: The Type C dial is the last of the gilt era and maintains almost all the characteristics of the Type A (Swiss Only) dial. See below for the subtypes and printing characteristics that distinguish one from the other. Most Type C dials are found in the shaped/rounded crown guard cases that are seen from 1964 onwards but early examples can still be seen with PCG/’Cornino’ cases.
*As the serial numbers increase into the 16xxxxx-172xxxx range, some collectors become suspicious. Most of these case numbers are matte dials, however there is a large overlap and I’ve seen several Type C gilts with 1.72m cases. I would, as always, buy the seller in these cases and be cautious, recognizing that if you want to sell it down the line, buyers may disagree with you and shy away.
Distinguishing Characteristics: As compared to the Type A dial, two font changes should be noted:
- The ‘Oyster Perpetual’ is evenly spaced on the Type C. As I noted on the Type A page, the ‘a’ in perpetual is the clearest place to note the difference.
- The Type C dial does not appear to come with additional markings, e.g. underlines or double swiss. Be very careful of aftermarket printing in those that do. I can’t say they don’t exist but buy the seller and vet those piece carefully.
As with all these gilt dials a variety of font widths can be seen as the printing pads became worn and had to be replaced – this phenomenon seems to be more notable on the Type C dial than other gilt dials. Some are very fat font and lose the serifs while others are skinny and retain the sharp edges (compare the first two examples below).
Subtypes: There are two subtypes to this dial based on the size and spacing of the “Swiss T<25,” which otherwise share the same fonts. Thus far, the serial ranges for these two subtypes appear to completely overlap – both are seen in early PCG cases and in the later half of the serial range.
- “Swiss T < 25” is spread over the bottom 3 minute hashes. This is the more common of the two.
- “Swiss T < 25” is spread over the bottom 5 minute hashes. This is less common and is referred to as a ‘wide swiss’** The ‘wide swiss’ example is the last example pictured below.
