VS3235 Movement Analysis: Why VSF's Caliber Dominates

Technical Analysis · Published 2026-07-24 · 1 min read

Technical Specifications

The VS3235 operates at 28,800 vph with a 70-hour power reserve. The balance wheel is a free-sprung Glucydur-style design with four timing screws. Amplitude from factory-fresh movements averages 295-310 degrees. The automatic winding uses a bidirectional rotor with ceramic ball bearings for reduced friction.

Accuracy Benchmarks

Based on timegrapher readings from 50+ samples, the VS3235 averages +3.2 seconds per day across all positions. Dial-up shows the best results (+1.5 to +3.0 s/d), while crown-down shows higher variation (+4.0 to +6.5 s/d). Rate stability over 48 hours is excellent.

Reliability Data

Field reports indicate a 12-month survival rate of approximately 95%. Common issues are limited to rotor noise amplification over time and occasional amplitude drop requiring regulation. Compared to the DD4130, the VS3235 shows the lowest failure rate in its category.
