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

Rigi 2300-EC in 1974 — geometric dial balance on the wrist

The 36 mm case and 44 mm lug-to-lug length give this Rigi more wrist presence than many conventional dress watches of its era. Its softly squared case surrounds a similarly shaped dial opening, producing a strong 1970s silhouette. The silver dial, dark-edged applied markers and polished steel exterior create a controlled monochrome palette, while the brown strap adds warmer contrast.

Silver sunburst dial with framed hour markers

The dial has a subtle silver sunburst finish radiating from the center. Applied square and rectangular hour markers sit around the perimeter with dark inner detailing, accompanied by small circular accents and a fine minute track. The RIGI signature appears below 12 o’clock with 17 JEWELS beneath it, while 2300-EC and INCABLOC are clearly printed in the lower half.

Faceted hands and central seconds

The hour and minute hands use narrow, faceted forms that suit the angular dial furniture and remain visible against the pale background. A slim central seconds hand extends toward the outer minute track. The handset continues the restrained silver-tone presentation, allowing the case geometry and marker layout to provide most of the visual character.

Stainless steel cushion case with architectural lugs

The confirmed stainless steel case combines a broad brushed upper surface with polished side areas around the perimeter. Straight, projecting lugs reinforce the angular form and connect naturally with the 19 mm strap. Light age-related marks are visible, while the distinctive square-cushion profile remains clear.

Ridged crown and purposeful exterior detailing

A ridged crown is positioned at 3 o’clock and provides practical grip for winding and setting. Its compact size keeps it visually subordinate to the broad case. No crown signature is clearly visible in the supplied image, so none is claimed. The crown and brushed case top support the watch’s functional design language.

New brown crocodile-embossed leather strap

The watch is fitted with a new brown leather strap with crocodile-embossed texture and tonal stitching. Its warm color softens the cool steel and silver dial while retaining a traditional dress-watch feel. The 19 mm width balances the broad case, and the adjustable fit makes the watch practical for regular wear.

AS 1950/51 manual-wind caliber with 17-jewel specification

Inside is the confirmed AS 1950/51 manual-wind caliber. The dial states 17 JEWELS and INCABLOC, directly confirming those two specifications. Manual winding gives the owner a simple mechanical routine through the crown, fitting the straightforward character of this 1970s Swiss watch.

Rigi 2300-EC and the angular language of 1970s Swiss design

Dated to 1974, this Rigi reflects a period when Swiss dress watches increasingly moved beyond purely round cases toward stronger geometric forms. The cushion-shaped stainless steel body, squared dial opening and applied marker layout place the design firmly within that decade while keeping the display highly legible.
