Presence & Behavior on the Wrist

The 41 mm stepped round case carries a cool, metallic sharpness when lifted from the surface and then softens once it settles onto the wrist. Light touches the bezel in a thin, continuous ring, never flashing or scattering. The polished lugs behave differently—they take light in vertical strokes, emphasizing length rather than width, which stabilizes the visual balance of the large calendar layout. KM Factory’s machining keeps these transitions crisp enough that the case reads as a layered object, not a single mass of steel.

The watch wears thinner than its 12.9 mm thickness suggests. The center case visually sinks between the bezel and the stepped caseback, letting the calendar complexity remain visually centered and not top-heavy. This is where the Traditionnelle silhouette shows its advantage: formal, upright, but never rigid.

The Dial: A Controlled Map of Functions

The dial of the 4010T complete calendar is a carefully aligned environment.

• Railway minute track gives the perimeter a framework, stabilizing the multiple calendar indications.
• Dauphine hands cut through the dial in two polished planes, catching light sharply at one angle and fading into silhouette at another.
• Day and month apertures, positioned at 9 and 3, create a lateral axis that divides the dial into two clean hemispheres.
• Peripheral date scale remains legible because the typography is thin, evenly spaced, and never competes with the hands.
• The black crescent date pointer introduces the only curve on the entire dial, adding a gentle piece of movement to a composition dominated by straight lines.
• Moon phase at 6 o’clock deepens the lower half of the dial, anchoring the visual weight and preventing the upper calendar windows from dominating.

KM Factory replicates all of these relationships in proportion—not only copying printing, but preserving spacing, alignment, and depth. Under angled light, the date numerals never appear crowded, and the moon-phase disc sinks just enough to create dimensionality without shadowing the surrounding surface.

Light, Texture, and the Quiet Behavior of a Formal VC Calendar

The 4010T generation behaves differently from the Patrimony or Overseas families. Traditionnelle is about structured order.

From a top view, the dial behaves like a technical instrument. But as the wrist moves, reflections soften the geometry and give the watch a warmer, more ceremonial presence. The silver dial does not glow; it diffuses. The polished hands and markers act as controlled reflectors, generating sharp but narrow highlights that remain readable even in low angles of light.

This controlled, almost academic approach to light is what gives the Traditionnelle its particular emotional register: calm, precise, learned, slightly formal, but never cold.

Movement Representation — The KM Factory 2460 Architecture

KM Factory uses its upgraded 2460-style automatic movement to reproduce the correct spatial layout associated with Vacheron Constantin’s in-house 2460 QCL. The bridges, gear locations, and rotor profile follow the geometry and behavior of the original architecture, giving the caseback the correct “VC mechanical density” rather than the open, flat appearance typical of lower-grade clones.

Winding feels smooth, without the abrupt mechanical jumps or resistance variations often found in non-Vacheron-based clones. The watch carries a clean central seconds behavior, stable date-index positioning, and consistent calendar engagement when transitioning near midnight.

This is one of KM’s strongest technical executions for the Traditionnelle category.

Wrist Personality & Dress Adaptation

On the wrist, the 4010T Complete Calendar behaves like a formal instrument rather than a decorative watch. The calendar functions create a sense of quiet capability—something designed to be used, not merely admired.

With darker leather, the look becomes archival and traditional. With blue alligator (as shown), the watch gains a subtle modernity without losing formality. The calendar display always remains the emotional center of the piece: calm—never urgent, never busy.

Why This Model Works Well as a Super Clone

Because the original 4010T relies on:

• exact spacing
• exact geometry
• exact step transitions
• exact calendar symmetry

…factory execution matters more than dial printing or lume tone. KM Factory’s strength is consistency of machining and alignment, making this particular model significantly closer to the genuine layout than many other VC complications.
