I realize that this is historical esoterica, but my research here took some unusual turns.
Shown above are four very early and rare IWC pocket watches, the Calibres 22, 24, 26 and 28. They most likely are from the period 1877 to 1882, a somewhat turbulent and certainly transitional period in IWC’s history, right after Jones.
The Calibre 22 “Seeland” was recently acquired, but it certainly doesn’t look like the “typical” Seeland (calibre 24, and also 26). Rather, it looks like an earlier Calibre 28, on the right. So I checked, and found an old e-mail from the late Fritz Wagener (“early iwc”) to me. He wrote me:
“According to expert's comprehension, (incl. Jürgen King) during the era F. Seeland there have been developed/built only the caliber "Boston" namely the c.24 –c.26. The caliber c.18 – c.23 are ascribed to the following period of Tschopp/Pfister”.
As usual, I think he may be right. if so, the early movements weren't always numbered in historical sequence.
By the way, by right clicking you can see a much larger view of the image.
