I see a 400 day clock sayhing “DeBruce” on the dial every now and then, and here is one I recently repaired, and polished the base. The back of the movement says “Royce Watch Co.” but Kundo made it and it is just like a Kundo standard 400 day clock
Repair job 8777. I polished the pivots and installed a new 0.0032 inch suspension spring (unit 1). Horolovar back plate no. 1503.
