What owners report2 reports on one topic

Forum posts and written reviews. Each covers one watch, so read them as things to check rather than a verdict.

The author distinguishes A/B/C. B has a scalloped bezel, decorated signed movement and bracelet attachment screws. Early examples reportedly ran about +30 seconds/day; later examples around +8/-8 seconds/day. These are period owner observations, not a current production spec.

A 2021 review of generic 9937 reports 40mm, 200m, flame-fusion crystal and ETA 2824-2/26 jewels. This differs from the 2009 B review and is not merged into the historical B variant.
