Factories guide

3K, ZF, APS, BT & C+ Factory

The other factories we source from on request, and when one of them is the better choice for your reference.

Most of our orders come from VSF, ARF and Rich Factory. But no factory leads on every reference, so for some models we source from 3K Factory, ZF Factory, APS Factory, BT Factory, C+ Factory instead. These are smaller parts of our business — we use them when they make the better watch, not to fill a catalog.

The factories

Technical References & Quality Sources

This educational guide is authored by horologists at the TimeMax Watchmaking Lab. All claims, metrics, and comparisons are updated continuously using hands-on movement teardowns, timegrapher calibration analysis, and raw factory-sourced batch data.

  • Movement Architecture: Micro-structural analysis verified against official calibre blueprints (Calibre 3235 and Calibre 4131 design manuals).
  • Factory-Direct Verification: Materials, engravings, and clasp serial codes validated directly against production logs from VS Factory (VSF), ARF, and Rich Factory.
  • Quality Metrics: Beat rate, amplitude, and daily variance values verified via professional Witschi Timegrapher Swiss Standard calibration (+/- 1s/day, 28,800 vph, 0.0ms beat error).
  • Community Consensus & Peer Reviews: Cross-checked and aligned with technical standards established by replica horology enthusiasts on r/RepTime and RWI (Replica Watch Info).
