Omikron, Ref. 3360, Cal. AS 1130, Men’s Manual Wind, 1966

Omikron 1966 — First impression - 3360

This Omikron reference 3360 presents a balanced mid-century design built around a 35 mm case, a 38 mm lug-to-lug span and an 18 mm strap width. The watch has a restrained dress-watch profile, yet the mixed applied numerals and baton markers give the dial more personality than a purely minimalist layout. The pale silver surface has a subtle radial effect and visible age-related character, while the warm metallic details soften the otherwise monochrome presentation. Its compact proportions are typical of the period and make the watch an appealing example of Swiss mechanical design from the 1960s.

Omikron - Silver Sunburst Dial

The dial is silver with a fine sunburst finish and visible vintage patina, especially around the outer perimeter and selected hour positions. Applied Arabic numerals appear at 12, 2, 4, 8 and 10, while rectangular markers occupy the remaining main positions. Small circular plots add another layer of visual structure near the minute track. The scripted Omikron signature sits below 12 o’clock with 21 RUBIS printed beneath it. At the lower edge, T SWISS MADE T is visible, directly identifying the Swiss dial origin and preserving an important period detail.

Omikron 3360 - Hands

The hour and minute hands are slim, faceted and aged in tone, with surfaces that show natural vintage oxidation and wear. Their length is well matched to the hour track, allowing the minute hand to reach close to the outer scale while the shorter hour hand remains easy to distinguish. A separate small-seconds display at 6 o’clock uses a fine central pivot and crosshair-style layout, reinforcing the traditional manual-wind architecture. The absence of a central seconds hand keeps the main dial uncluttered and gives the watch a more formal mid-century rhythm.

Omikron 3360 - Slim Round Case

The silver-tone case has a conventional round body with narrow polished bezel and long tapered lugs. At 35 mm in diameter, it remains compact by modern standards, but the 38 mm lug-to-lug length gives it a neat, proportional stance on the wrist. The case shows light age-related marks and surface wear visible in the photograph, consistent with a watch that has survived several decades without being over-restored. Because the exact case material is not confirmed in the supplied information, no stainless-steel or plated-case claim is made.

Omikron 3360 - Crown

A ridged crown sits at 3 o’clock and provides the grip needed for regular winding and time setting. Its warm tone contrasts slightly with the case and visually echoes some of the dial furniture. No clear crown signature is visible, so the listing does not describe it as signed. The crown size is practical for a manual-wind watch and suits the compact proportions without disrupting the profile of the case.

Omikron Black Leather Strap

The watch is fitted with a new high-quality black leather strap. Its lightly textured surface and dark stitching keep the presentation understated, allowing the silver dial and applied numerals to remain the visual focus. The 18 mm width fits the case proportions well and the adjustable design makes the watch suitable for a practical range of wrist sizes. The strap is a replacement component and is therefore described separately from the watch’s confirmed original components.

Omikron 1966 - Swiss Manual Wind AS 1130 with Small Seconds

The movement is identified in the supplied product information as the A. Schild AS 1130, a Swiss manual-wind caliber. This watch is confirmed as serviced and fully operational, making the movement specification relevant to practical ownership rather than historical interest alone. The dial clearly states 21 RUBIS, so the 21-jewel marking is recorded as a visible feature of this particular watch. The small-seconds configuration at 6 o’clock is consistent with the traditional architecture of the piece. No unsupported frequency or power-reserve figure is added. Collectors interested in similar mechanical formats can browse our manual-wind vintage watches with classic small-seconds layouts.

Heritage of the Omikron in Mid-Century Swiss Watchmaking

Omikron is a name familiar to many collectors in Southeastern Europe, where Swiss watches of this type were widely worn as practical everyday mechanical timepieces. This 1966 example reflects that context through its compact proportions, traditional hand-wound movement, mixed numeral dial and restrained case design. Rather than relying on a famous complication or oversized case, its appeal comes from the combination of period typography, visible mechanical identity and the subtle aging of original surfaces. The 21 RUBIS dial signature, T SWISS MADE T marking and small-seconds layout give it a strong period character. More examples from the brand can be viewed in our Omikron vintage watches with authentic 1960s Swiss character.
