Omikron Military Style, Ref. 3358, Cal. UT 6525, Men’s Manual Wind

Omikron Military Style 1966 — bold numerals in compact proportions

At 35 mm across and 42 mm lug to lug, this Omikron has classic mid-century dimensions with enough length to sit confidently on the wrist. The round case, narrow polished bezel and tapered lugs keep the profile restrained, while the black dial and large warm-tone Arabic numerals create a much stronger visual presence. The 18 mm strap width gives the case a balanced transition into the leather.

Glossy black dial with full Arabic numeral layout

The dial uses a deep black field with applied gold-tone Arabic numerals around the hours. Their sculpted forms give the watch a clear military-inspired appearance without losing its dress-watch refinement. A printed outer track includes minute divisions and five-minute numerals. The scripted Omikron signature and 21 RUBIS text sit below 12 o’clock and remain clearly legible against the dark background.

Small seconds and pale central hands

A subsidiary seconds register at 6 o’clock introduces a traditional manual-wind layout. The small register uses simple white divisions and a fine seconds hand. Pale hour and minute hands provide strong contrast against the black dial and reach cleanly toward the applied numerals, giving the display direct readability while preserving its vintage character.

Round case architecture with long tapered lugs

The silver-tone case has a circular body framed by long, sharply tapered lugs. A slim polished bezel keeps the dial visually dominant. Surface marks and light scratches are visible on the exterior and are consistent with normal age and use. Because the exact case material is not confirmed in the supplied data, no stainless-steel or plated-case claim is made.

Ridged crown shaped for regular winding

A ridged crown sits at 3 o’clock and offers practical grip for winding and time setting. Its scale suits a hand-wound watch, where interaction with the crown forms part of regular ownership. No crown signature is clearly visible in the supplied photograph, so no signed-crown claim is made.

New black leather strap at 18 mm

The watch is fitted with a new black leather strap with a lightly textured surface. Its dark tone continues the dial color and gives the warm numerals additional contrast. The 18 mm width works naturally with the elongated lugs, while the adjustable fit makes the watch straightforward to wear. The strap is a replacement component; the watch itself is confirmed as retaining all original watch components.

UT 6525 manual-wind caliber and visible 21 RUBIS marking

The movement is confirmed as the UT 6525 manual-wind caliber. The dial itself states 21 RUBIS, allowing the jewel marking to be included as a visible, confirmed feature. No power reserve or frequency is supplied, so those specifications are omitted. The watch is listed as serviced and fully operational. Collectors can compare it with our manual-wind vintage watches with small-seconds layouts.

Military-inspired Omikron design from 1966

The 1966 production year places this piece firmly in the mid-century Swiss mechanical era. Its full Arabic numeral layout, black dial, outer minute scale and subsidiary seconds create a purposeful visual language, while the polished case and applied numerals retain enough refinement for dress wear. The dial also carries T SWISS MADE T at the lower edge. Related pieces appear among our Omikron vintage watches with 1960s Swiss mechanical character.

Serviced originality and present condition

This Omikron is confirmed as serviced and fully operational, with all original watch components retained. The black leather strap is new and is not represented as an original period component. The glossy dial remains highly legible and shows light age-related character, while the case carries normal surface wear visible in the supplied image. No box or papers are included. A 12-month warranty accompanies the watch.
