IBench notes
Crystal · dial · hands
Small tolerances
reward slow hands.
Challenge
Sourcing
Verifying every part against the real NH35 footprint before it shipped, not the marketing copy.
Challenge
Hand setting
Press too hard and you scratch the dial; too soft and the hand slips at six.
Learnt
Patience pays
Rushing always meant starting over. Slow, deliberate hands every time.

IIINothing arrived assembled
Seven parts,
sourced separately.
Most parts marketed for the NH35 actually aren't. Stem lengths, dial feet and hand-hole sizes all had to match before anything shipped. Each was checked against the movement, then assembled under a loupe in a sealed, dust-free room.
