Brand
Tudor (subsidiary of Rolex SA). High-tier luxury brand known for 'Rolex quality' at a more accessible price point using outsourced movements.
Movement
Quartz Caliber (likely ETA 955.112 base). This is an ultra-reliable, high-grade Swiss quartz movement with a quick-set date function, hacking seconds, and approximately a 2-3 year battery life.
Dimensions
34mm Diameter, 9.5mm Thickness, 41mm Lug-to-Lug, 19mm Lug Width. It wears slightly larger than its dimensions suggest due to the Oyster case and prominent bezel, fitting like a classic 35mm watch.
Description
The Tudor Prince-Quartz Oysterdate is a masterclass in understated versatility. It carries the DNA of the Rolex Datejust but embraces the precision of the quartz era. Its monochromatic white and steel appearance makes it an ideal daily wearer that transitions perfectly from casual to formal settings.
Key Features
Engine-turned steel bezel, Buckley-style Roman numeral dial, Oyster case architecture, Tudor Shield branding, and the Cyclops date magnifier.
Dial Description
White 'Buckley-style' dial featuring printed black Roman numerals. Baton-style hands with luminous inserts, central sweeping seconds, and a date window at 3 o'clock. Includes the Tudor Shield logo at 12.
Case Material
Stainless Steel (316L). The case features a brushed satin finish on the lug tops with high-polished case flanks. The engine-turned bezel is also stainless steel.
Crystal Type
Sapphire crystal (flat) featuring a Cyclops magnification lens over the date. Excellent condition with no visible scratches or chips.
Bezel Details
Fixed engine-turned bezel in stainless steel. It features decorative fluting/reeding that provides a distinctive texture and high-frequency light reflection.

Screw-down 'Twinlock' crown with the Tudor Shield logo. Integrated crown guards formed by the sloping oyster case-side.

Water Resistance
100 Meters (330 Feet). Theoretically suitable for swimming, but vintage seals should be professionally inspected before water exposure.
Origin & Provenance
Swiss Made. Manufactured in Geneva, Switzerland. Movement is a Swiss-made high-grade caliber from ETA, modified or regulated for Tudor.
Age Estimate
Circa 1990-1995. The use of 'T-SWISS-T' or 'SWISS' markings and the transition to sapphire crystals suggest late production of the Oysterdate quartz line.
Cultural Significance
A bridge between the mechanical tradition of Rolex and the technological advancement of the 20th century. It represents Tudor's historical role as the 'testing ground' for durable luxury designs for a wider audience.
Condition Notes
Very Good. The case shows sharp lines suggesting minimal polishing. The dial is clean with no visible debris. Bracelet shows minor surface scuffing consistent with careful wear.
Value Estimate
$1,400 - $2,200 USD. Value is driven by the condition of the engine-turned bezel and the presence of the original bracelet.
Care & Maintenance
Battery changes every 2 years are vital to prevent leakage. Gaskets should be pressure tested every 3 years. Avoid high-strength magnetic fields which can temporarily stall quartz motors.
