Blicquer Supporter 90 · July 14, 2022

Serial Number B0261431 was reported as inaccurate.

Note: Sorry, should have caught this before I verified
this before. Jewel count is 15J on this example,
not 17, as confirmed by the watchmaker who cleaned
it, and because there is no pillar plate jewel for
the center wheel arbor.
