Design
- Dial and Hands
- The watch is equipped with a MK2 Black Sigma dial, featuring a three-register layout with contrasting white subsidiary registers and white printed text. The dial includes tritium hour plots that show signs of aging. The presence of small Greek sigma symbols at the six o'clock position, positioned on either side of the 'T SWISS T' signature, indicates that the hour markers and hands are fashioned from white gold. These sigma markings were introduced during the 1970s to denote the use of gold components.
