This 34 mm Tudor Royal stands out for the combination of an integrated steel case and bracelet, a decorative fluted bezel and a silver sunray dial.

The dial features eight diamond hour markers. At 12, 6 and 9 o'clock there are applied Roman numerals, while the date position at 3 o'clock replaces the fourth Roman numeral.

The combination of brushed and polished surfaces runs from the case through the integrated five‑row bracelet.

The watch is offered as a full set with the accompanying Tudor presentation and documentation.

──────────────────

Case

The case is made of 316L stainless steel and has a diameter of 34 mm.

The Royal features an integrated case design where the steel bracelet attaches directly to the case. The top sides of the case are mostly satin-finished, combined with polished sections for contrast.

The case shows light signs of wear and fine minor scratches consistent with normal wear. There are no obvious heavy damages visible.

──────────────────

Bezel

One of the hallmarks of the Tudor Royal is the fixed fluted bezel.

It consists of alternating polished faces and finely milled grooves. This makes the bezel’s appearance change with the angle of light.

The polished portions show light superficial signs of wear, but the bezel’s structure is nicely preserved.

──────────────────

Dial

Silver-colored sunray dial with a fine radial finish from the center.

The hour markers are eight separately set diamonds, combined with applied Roman numerals at 12, 6 and 9 o'clock.

Also featuring:
Tudor shield logo
TUDOR GENEVE inscription
Minute track along the outer edge
Date window at 3 o'clock
SWISS MADE inscription at 6 o'clock

The silvered hands have a contrasting dark outline and are equipped with luminous material.

The dial is in very neat condition.

──────────────────

Diamond hour markers

This Royal 34 edition features eight diamond hour markers.

The diamonds are individually set in round metal settings and alternate with the three applied Roman numerals. This keeps the dial relatively understated while the diamonds stand out in direct light.

──────────────────

Date

At 3 o'clock there is a separate date window with a silver-colored outline.

The date is shown in black on a light background, thus matching well with the silver dial.

──────────────────

Movement

The watch is powered by the automatic Tudor caliber T601.

Type: automatic mechanical
Caliber: T601
Frequency: 28,800 vph / 4 Hz
Jewels: 25
Power reserve: approx. 38 hours
Central hours, minutes and seconds
Date function
Stop-seconds function for precise time setting

The movement is automatically wound by wrist movement and can also be wound via the crown.

Timegrapher measurement

The performed measurement shows:
Rate deviation: +5 seconds per day
Amplitude: 287°
Beat error: 0.0 ms
Lift angle: 52.0°
Frequency: 28,800 vph

These are neat measurement values at the test moment. A timegrapher measurement is always a snapshot and does not constitute a warranty for future accuracy or the full technical state of the movement.

──────────────────

Crown

The Royal is equipped with a screw-down steel crown.

On the outer side of the crown is the Tudor logo in relief. The screw-down construction contributes to the water resistance of 100 meters as specified in the model.

An up-to-date water resistance test is not part of this listing; the factory specification should not be considered a warranty of current water resistance.

──────────────────

Case back

Closed stainless steel case back with surrounding multiple Tudor Geneva logos and inscriptions.
The reference 28400 and the individual case/serial number are also stamped on the case.
The back shows light scratches and signs of wear appropriate to normal use.
──────────────────

Stainless steel bracelet

Integrated Tudor bracelet in 316L stainless steel with five links.
The bracelet combines satin-finished outer and middle links with narrow polished inner links. This variation visually aligns with the mix of matte and polished surfaces on the case and bezel.
The bracelet shows light signs of wear and fine scratches, especially on the polished parts.
Extra links are included.
──────────────────

Clasp

Tudor stainless folding clasp with safety lock.
The clasp features a clear Tudor inscription and combines brushed and polished surfaces.
On the clasp there are light superficial scratches from normal use.
──────────────────
