Delbana, Cal. AS 1951, Men’s Manual Wind Vintage Watch

Delbana 1965 — balanced mid-century wrist presence

With a 34 mm case diameter and 40 mm lug-to-lug length, this Delbana sits firmly within the restrained proportions of 1960s Swiss watchmaking. The round silver-tone case is paired with angular lugs and a narrow polished bezel, allowing the dial to occupy most of the visual area. Its combination of a pale dial, warm applied furniture and dark strap gives the watch a composed dress-watch character without making the design overly formal.

Silver sunburst dial with applied numerals and batons

The dial has a silver sunburst finish that radiates from the center and changes subtly with the light. Applied gold-tone baton markers are joined by Arabic numerals at 12, 9 and 6, creating an immediately recognizable period layout. The Delbana name and castle-style emblem sit below 12 o’clock, while the lower half carries the clearly visible 17 JEWELS and INCABLOC inscriptions. At the dial edge, T SWISS MADE T provides another authentic visual detail from the period.

Framed date window and luminous handset

A date aperture at 3 o’clock is surrounded by a dark double-line frame, giving the calendar display strong definition against the silver background. The hour and minute hands have slim luminous inlays, while a fine central seconds hand keeps the display visually light. Together with the applied markers, the handset preserves strong legibility without disrupting the open dial composition.

Case architecture with clean angular lugs

The case uses a conventional round central body but gains character from straight, faceted lugs that extend cleanly toward the strap. Light age-related marks are visible on the exterior and bezel, 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. The 16 mm lug width keeps the strap narrow and appropriate to the watch’s original proportions.

Large ridged crown for daily hand winding

The crown at 3 o’clock has pronounced ridging and a relatively generous diameter, making it easy to grip during the regular winding routine required by a manual watch. No crown signature is clearly visible in the supplied image, so the listing does not describe it as signed. Its practical shape fits the straightforward mechanical nature of the watch.

New black leather strap with blue stitching

A new high-quality black leather strap is fitted to the 16 mm lugs. Subtle blue stitching follows the edges and adds a small contemporary accent while leaving the watch head visually dominant. The strap is adjustable and provides an uncomplicated wearing solution for a compact vintage case. It is a replacement strap; the watch itself is confirmed as retaining all original watch components.

AS 1950/51 — 17-jewel Swiss manual-wind movement

The watch is powered by the confirmed A. Schild AS 1950/51 caliber, a Swiss manual-wind movement specified with 17 jewels, a frequency of 21,600 beats per hour and an approximate 46-hour power reserve. The INCABLOC marking visible on the dial identifies the stated shock-protection feature. The movement has been serviced and the watch is confirmed as fully operational, giving the mechanical specification practical relevance rather than serving only as period detail.

Delbana design language from the mid-1960s

This 1965 example combines several signatures associated with accessible Swiss mechanical watches of its era: compact dimensions, applied dial furniture, a framed date display, hand-wound movement and restrained exterior styling. The layout feels purposeful rather than decorative, with the date and jewel information integrated cleanly into the dial. Buyers comparing the maker can browse our Delbana vintage watches with 1960s Swiss mechanical character, while collectors focused on the winding format can explore manual-wind vintage watches with traditional mechanical operation.

Serviced originality and ownership details

This Delbana is confirmed as serviced, fully operational and fitted with all original watch components. The black leather strap is new and is not presented as an original period component. The watch is offered without box or papers and includes a 12-month warranty. Its silver dial remains attractive in presentation, while minor marks on the case and exterior reflect normal age-related use rather than being hidden by exaggerated condition claims.
