AS 1950\/51, Men’s Manual Wind","description":"\u003cp\u003eVintage Rigi 2300-EC dress watch from 1974 combines a silver sunburst dial, applied geometric markers and the AS 1950\/51 manual-wind caliber in a distinctive stainless steel cushion-shaped case. This Men’s Swiss Made mechanical watch is offered for sale with visible 17 JEWELS and INCABLOC signatures, refined period proportions and a new brown leather strap.\u003c\/p\u003e\u003ch2\u003eRigi 2300-EC in 1974 — geometric dial balance on the wrist\u003c\/h2\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003ch3\u003eSilver sunburst dial with framed hour markers\u003c\/h3\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003ch3\u003eFaceted hands and central seconds\u003c\/h3\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003ch2\u003eStainless steel cushion case with architectural lugs\u003c\/h2\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003ch3\u003eRidged crown and purposeful exterior detailing\u003c\/h3\u003e\u003cp\u003eA 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.\u003c\/p\u003e\u003ch3\u003eNew brown crocodile-embossed leather strap\u003c\/h3\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003ch2\u003eAS 1950\/51 manual-wind caliber with 17-jewel specification\u003c\/h2\u003e\u003cp\u003eInside 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.

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.
