**SPECIFICATIONS** **Brand:** Tudor **Model:** Submariner **Reference:** 79090 **Year:** 1991 **Case Number:** B377117 **Case Material:** Stainless steel **Diameter:** 40 mm **Lug Width:** 20 mm **Thickness:** 12.2 mm **Lug-to-Lug:** 47.5 mm **Dial:** Blue **Lume:** Tritium **Crystal:** Acrylic **Movement:** Automatic **Caliber:** ETA 2824-2 **Bracelet/Strap:** Tudor 9315 stainless steel bracelet with 380B end links and O12 clasp code **Max Wrist Size:** 7.25 in (11 links) **CONDITION** **Case:** The stainless steel case shows normal signs of wear for a watch this age including a few hairlines, faint scratches, and micro nicks, the most notable of which are on the case sides. However, the overall impression is clean. The lugs are thick and well-defined with chamfers still present. There is a small ding to the bottom edge of the lug at 1 o'clock. The bezel insert has slightly faded to a lovely pale blue color and is in superb condition with no notable marks. The caseback condition is consistent with the rest of the watch, exhibiting tiny scratches and nicks throughout. The backs of the lugs show faint signs of prior bracelet removal. The Rolex engravings remain sharp and legible. **Dial, Hands, & Crystal:** The glossy blue dial and polished Mercedes hands are in excellent condition, with the latter exhibiting a couple micro imperfections only visible upon close inspection. The tritium lume plots are matching with a light creamy color. The lume plot of the seconds hand shows a small crack, but remains intact. When exposed to UV light, neither the dial, hands, or bezel lume plot exhibit any glow. The acrylic crystal is strong and clean with only a few faint signs of wear and an unremovable piece of debris at edge at 6 o'clock. **Bracelet/Strap:** The Tudor stainless steel bracelet exhibits minor stretching, but is still in very good condition. The clasp has some light scratches and desk-diving marks and the links show light signs of wear throughout. The link closest to the case at 12 o'clock exhibits a faint bend. The clasp code of O12 is a close match with the case number, the end links are correctly stamped 380B, and the 9315 reference marking is present underneath the first link at 12 o’clock. The Tudor stamp at the clasp remains sharp and detailed. **MOVEMENT** **Timing:** The watch has been measured with a timegrapher at six different positions. The rate, amplitude, and beat error are within acceptable ranges. While resting face up, the rate is +1s/d. **Functions:** All functions including the crown winding, time setting, and date changing are working as expected. **Service History:** The watch recently underwent a full service by D's Time Service that was completed on 05/02/2024. **WHAT'S INCLUDED** Pictures: [https://imgur.com/a/R7zfutf](https://imgur.com/a/R7zfutf) Timestamp: [https://imgur.com/a/dynoohG](https://imgur.com/a/dynoohG) **PRICE & DELIVERY** I'm asking **$7,700** net to me via bank transfer, Zelle, or PayPal + fees.
