Important details

This 34 mm Tudor Royal stands out for the combination of an integrated stainless steel case and bracelet, a decorative knurled 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 window at 3 o'clock replaces the fourth Roman numeral.

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

Year: 2021

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 has an integrated case design with the stainless steel bracelet directly joining the case. The upper sides of the case are mainly satin-finished, combined with polished parts for contrast.

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

──────────────────

Bezel

One of the defining elements of the Tudor Royal is the fixed knurled bezel.

It consists of alternating polished planes and fine milled grooves. This changes the bezel’s appearance depending on the light.

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

──────────────────

Dial

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

The hour markers consist of 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 markers 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 luminescent material.

The dial is in very good condition.

──────────────────

Diamond hour markers

This Royal 34 variant 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 come forward in direct light.

──────────────────

Date

There is a separate date window at 3 o'clock with a silver-colored rim.

The date is displayed in black on a light background and thus matches well with the silver dial.

──────────────────

Movement

The watch is powered by the automatic Tudor caliber T601.

Type: mechanical automatic
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 the motion of the wrist 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 time of testing. A timegrapher measurement is always a snapshot and does not constitute a guarantee of future accuracy or the full technical condition of the movement.

──────────────────

Crown

The Royal features a screw-down stainless steel crown.

On the outside of the crown is the Tudor logo in relief. The screw-down construction contributes to the water resistance of 100 meters as stated in the model specification.

An actual water resistance test is not part of this listing; the factory specification should not be taken as a guarantee of current water resistance.

──────────────────

Caseback

Closed stainless steel case back with multiple 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 wear consistent with normal usage.
──────────────────

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 center links. This variation 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 clear Tudor inscription and combines brushed and polished surfaces.
On the clasp there are light superficial scratches due to normal use.
──────────────────

Wrist size

In the current configuration, the bracelet fits a wrist circumference of approximately 16.5–17 cm.
Additionally, loose extra links are provided so the band can be extended further.
