Coming back to Caliber 89... the makers we've discussed so far are all so close, but there is no match so far.

For me the sticking point is the cutaway around the setting works: in all our proposed sources, it tapers in close to the gears; in the Cal 89 it does not.

I would like to propose a new possible source: Camille Pourrat & Fils (C. Pourrat Fils), out of Geneve. He was also finishing Lecoultre ebauches in fine grades. He was active as a maker and a representative (beside Vacheron & Constantin and Lavina's own Paul Brack) of Swiss watchmaking from 1910 until his death in 1923.

He assumed his father's company (J. Pourrat & Fils), continuing to use its mark: JP & F

But here is a look at his much earlier pocket watch setting bits (a lever set Lecoultre 6). Apologies for the low res, but it's taken lots of looking to find anything at all.

Finding his work will be difficult, let alone in a matching size: in the teens & twenties he appears to be making for others vs. branding his own. Hoping others may have better luck.
