Description:

1976 Rolex Datejust Thunderbird 1625 Turn-O-Graph Sigma Dial Two Tone Jubilee Wristwatch. Steel Oyster case is very nice and has remained thick with well defined bevels and edges. Some expected wear from usage. Solid 14k yellow gold Turn-O-Graph bezel is incredibly crisp. Original silver Sigma Pie Pan Datejust dial is in excellent condition. Tritium on both hands and dial is original and have aged to a gorgeous warm hue. Tritium glows brightly when exposed to UV and falls off rapidly at the same pace. 20mm two tone USA Steel and 14K yellow gold Jubilee bracelet is nice, has some expected wear and stretch, and will fit 7.5" wrist size. Crown is crisp and winds smoothly. Caliber 1570 Oyster Perpetual automatic movement has been freshly serviced.
