- Case and Dial Design
- The wristwatch utilizes a 36mm stainless steel Oyster case. A hallmark of the reference 1601/3 is the 18-karat yellow gold fluted bezel, which contrasts against the steel middle case and lugs. The dial is a matte blue finish with a stepped 'Pie-pan' geometry. Gold-tone indices are applied, with the markers at the six and nine o'clock positions appearing notably wider. Sigma symbols flanking the 'T SWISS T' text signify the use of precious metals for indices and hands, a convention used in the 1970s.
- Movement and Bracelet
- The movement is a self-winding automatic caliber characterized by a 'slow-setting' date mechanism. According to the provided source, the internal mechanism has been fully serviced by a watchmaker to ensure functional performance. The timepiece is fitted with a folded Jubilee bracelet, designated as reference 6252H. The bracelet attaches to the case using 255-reference end links, maintaining visual and technical consistency with the manufacturing era of the watch.
- Technical Verification
- This includes an independent assessment of the case edge finishing, which may have been affected by previous polishing, and the authenticity of the Sigma dial prints. It is suggested that the reference alignment between the case and the bracelet be checked to confirm the assembly remains consistent with factory standards of the period.
