Rigi 2300-EC, Cal. AS 1950/51, Men’s Manual Wind

Rigi 2300-EC — vivid 1973 contrast in a broad case

The 35 mm case is unusually compact from lug to lug at 35 mm, giving this Rigi a short, broad stance on the wrist. Its brushed silver-tone body surrounds a round dial opening, while the black center and bright orange outer track create a strong visual contrast. The 20 mm lug width adds further presence and makes the watch feel more substantial than its nominal diameter suggests.

Black dial with orange peripheral scale

The dial uses a deep black field surrounded by a saturated orange chapter ring. Fine dark minute divisions run around the orange perimeter, with small luminous-style circular accents positioned near the hour markers. Applied silver-tone rectangular markers project clearly from the dark background. The RIGI signature and 17 JEWELS text sit below 12 o’clock, while INCABLOC and 2300-EC are printed above the lower half.

Framed date and broad central handset

A framed date aperture at 3 o’clock provides the calendar display and is emphasized by a bright rectangular border. Broad hour and minute hands use pale inserts for contrast, while a slender central seconds hand reaches toward the outer scale. The combination of large markers, wide hands and the orange track gives the watch a practical, highly legible layout with unmistakable period styling.

Brushed case architecture and 20 mm strap proportions

The exterior has a broad, angular profile with a vertically brushed upper surface and polished side areas that catch the light along the case edges. Its shape is characteristic of the early 1970s, when Swiss watch design often moved beyond conventional round dress cases toward wider geometric forms. Light surface marks are visible, but the case retains a clean overall presentation. The exact case material is not confirmed, so no stainless-steel claim is made.

Ridged crown for regular hand winding

A compact ridged crown sits at 3 o’clock and provides the grip required for winding and time setting. Its scale is restrained relative to the broad case, keeping the profile neat. No visible crown signature can be confirmed from the supplied photograph, so the listing does not describe it as signed.

New black leather strap with red stitching

The watch is fitted with a new high-quality black leather strap with bright red stitching along both edges. That red accent complements the warm orange dial track without duplicating it exactly, giving the watch a cohesive but not overly matched appearance. At 20 mm wide, the strap balances the broad case well and provides an adjustable fit for practical everyday wear.

AS 1950/51 manual-wind caliber with confirmed specifications

The movement is identified as the A. Schild AS 1950/51, a manual-wind Swiss caliber. The supplied product data confirms 17 jewels, a frequency of 21,600 vibrations per hour and an approximate 46-hour power reserve. The dial also visibly carries the 17 JEWELS and INCABLOC markings. The watch is listed as serviced and fully operational, giving these mechanical specifications direct relevance to ownership rather than serving only as historical detail.

Rigi 2300-EC and the sportier side of 1970s Swiss design

Dated to 1973, this example stands apart from restrained silver-dial dress watches through its black-and-orange color scheme, broad brushed case and high-contrast marker layout. The design remains simple in function, but its execution gives it a noticeably sportier visual character.
