After two months, I finally finished my brother’s 15407 double balance wheel.
Adjusting the dual‑balance structure was way more troublesome than a normal movement – just getting the two balances synchronized took several all‑nighters.
But in the end, the timing is stable, the amplitude is symmetrical, and the layered look through the caseback is spot on.
Thank you for your patience, brother – not a single nag in two months. That kind of trust means more than anything.
When you’re happy with the watch, that’s when my work is truly worth it.
