Omikron, Ref. 3360, Cal. AS 1130, Men’s Manual Wind

Omikron 3360 — mid-century balance in a 35 mm format

The 35 mm case and 38 mm lug-to-lug measurement give this Omikron compact proportions typical of its era, while the long tapered lugs add enough visual length to keep the watch well balanced on the wrist. A narrow polished bezel leaves most of the front surface to the dial, and the contrast between the pale face, warm applied furniture and dark strap creates a controlled dress-watch presentation rather than a heavily decorative one.

Cream dial with mixed numerals and baton markers

The dial has a warm cream tone with visible age-related character. Applied gold-tone Arabic numerals appear at 12, 3 and 9, while slim baton markers define the remaining principal hours. A fine printed minute track runs around the perimeter. The scripted Omikron signature and 21 RUBIS marking sit below 12 o’clock, giving the upper half a period-specific identity without crowding the display.

Concentric small seconds at six

The subsidiary seconds register at 6 o’clock is distinguished by closely spaced concentric rings, adding texture to an otherwise restrained dial. Its fine seconds hand and crosshair-style markings provide a technical counterpoint to the applied hour furniture. Slender faceted gold-tone hour and minute hands complete the display, with the separate seconds layout reinforcing the traditional manual-wind character of the watch.

Polished round case with elongated lugs

The silver-tone case uses a conventional round center but gains personality from long, sharply tapered lugs. A slim polished bezel surrounds the crystal and keeps the profile visually light. Surface marks and light scratches are visible on the exterior, consistent with normal vintage use. Because the exact case material is not confirmed in the supplied data, no stainless-steel or plated-case claim is made.

Ridged crown for a tactile winding routine

A compact ridged crown sits at 3 o’clock and provides the grip needed for regular winding and time setting. Its simple form suits the practical construction of the watch and does not interrupt the narrow case profile. No visible crown signature can be confirmed from the photograph, so the listing makes no signed-crown claim.

New black textured leather strap

A new high-quality black leather strap is fitted between the 18 mm lugs. Its pronounced textured pattern gives the watch a slightly sharper finish while keeping the focus on the cream dial and gold-tone details. The strap is adjustable for practical wear and is treated as a replacement component, while the watch itself is confirmed as retaining all original watch components.

AS 1130 manual-wind movement and 21-jewel dial signature

The movement is identified in the supplied data as the A. Schild AS 1130, a manual-wind Swiss caliber. The dial itself clearly states 21 RUBIS, so the jewel marking is included as a confirmed feature of this example. The watch is listed as serviced and fully operational. Collectors comparing similar hand-wound pieces can browse our manual-wind vintage watches with traditional small-seconds layouts.

Omikron 3360 in the context of 1960s Swiss design

Dated to 1966, this reference reflects the restrained proportions and clear dial organization associated with mid-century Swiss wristwatches. The mixed numeral-and-baton layout, separate seconds register and slim case architecture give it a recognizable period identity without relying on excessive ornament. Buyers interested in the maker can also explore our Omikron vintage watches with 1960s Swiss mechanical character.

Serviced originality and present-day ownership

This Omikron is confirmed as serviced, fully operational and fitted with all original watch components. The black leather strap is new and is therefore not presented as an original period component. The dial shows visible vintage aging, while the case carries normal surface wear and scratches. No box or papers are included. A 12-month warranty accompanies the watch, adding practical reassurance to a compact mechanical piece with clear mid-century character.
