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 directly attaches to the case. The top sides of the case are mainly satin-finished, combined with polished parts for contrast.

The case shows light signs of use and fine superficial scratches consistent with normal wear. No prominent heavy damage is visible.

──────────────────

Bezel

One of the distinctive elements of the Tudor Royal is the fixed fluted bezel.

It consists of alternating polished facets and fine milled grooves. This causes the bezel’s appearance to change with the light angle.

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

──────────────────

Dial

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

The hour markers consist of eight individually 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 silver hands have a contrasting dark outline and are equipped with luminous material.

The dial is in very nice condition.

──────────────────

Diamond hour markers

This Royal 34 model is equipped with eight diamond hour markers.

The diamonds are set in individual round metal settings and alternate with the three applied Roman numerals, keeping 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 border.

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: mechanical automatic
Caliber: T601
Frequency: 28,800 A/h / 4 Hz
Jewels: 25

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 A/h

These are tidy measurements at the test moment. A timegrapher reading is always a snapshot and does not constitute a guarantee of future accuracy or the full technical condition 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 stated water resistance of 100 meters according to model specification.

A current waterproofness test is not part of this listing; the factory specification should not be considered a guarantee of current water resistance.

──────────────────

Case back

Closed stainless steel case back with numerous Tudor Genève logos and inscriptions around the edge.
The reference 28400 and the individual case/serial number are also marked on the case.
The back shows light scratches and signs of use consistent with normal wear.

──────────────────

Stainless steel bracelet

Integrated Tudor bracelet in 316L stainless steel with five links.
The bracelet combines satin-finishing on the outer and middle links with narrow polished center links. This alternation visually matches the matte and polished surfaces of 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 steel folding clasp with safety lock.
The clasp features a distinct Tudor inscription and combines brushed and polished surfaces.
On the clasp there are light superficial scratches from normal use.
