Premium Hour Wheel H4, H5, H6 Compatibility for ETA2836 & ETA2834 Movements – Precision Engineering for Reliable Timekeeping
The modern and simple design of the H4–H6 hour wheels emphasizes functionality without compromising aesthetics. Their cleanly machined teeth and uniform surface finishing enhance meshing efficiency while reducing wear on adjacent components like the center wheel and minute wheel. This careful engineering ensures quiet operation and consistent evolution of motion transfer — essential for achieving the fluid sweeping motion watch enthusiasts appreciate in high-grade mechanical timepieces. Whether refurbishing a vintage chronograph or assembling a bespoke limited edition, this series complements diverse design languages —/tooling ready for minimalist, classic, or contemporary dial layouts.
Crafted from premium brass or stainless steel alloys (depending on variant), the wheels resist corrosion, deformation, and seasonal expansion issues common in entry-level replacements. With tolerances held within ±0.02mm, each wheel maintains dimensional stability across temperature shifts and daily use. The compatibility list includes popular ETA-based movements found in brands such as Sellita SW200-1 clones, Seiko NH series derivatives, and factory-grade calibers used across the mid-tier Swiss and Asian watch markets. This makes the H4/H5/H6 series a versatile inventory staple for any horologist focused on dependable service outcomes.
For professionals, the benefits extend beyond repair — these wheels support creative horological experiments. Swapping in a slightly larger or differently indexed hour wheel can subtly alter the feel of the time-setting action, offering fine-tuning opportunities alongside traditional adjustments like beat rate or poising. Combined with clean, modern finishes, they also provide excellent visual continuity for open-heart or skeletonized dial designs where the gear train is on display. Ultimately, the H4–H6 series bridges precision engineering with accessible craftsmanship, empowering makers and restorers to deliver reliable, refined timepieces — one well-meshed gear at a time.
