## Estimated production year

Estimated production period: Around the 2000s.

Without additional dated documentation, the exact production year of this specific watch cannot be confirmed.

## Watch case

The round watch case is made of stainless steel and has a diameter of 40 mm.

The case features a robust yet elegant design. The polished bezel flows into a relatively solid mid-case with clearly defined lugs.

The crown and two chronograph pushers are located on the right side. The pushers have dark inserts that create an attractive contrast with the polished stainless steel.

The case is in used condition and shows visible signs of wear.

There are scratches, fine micro-scratches, and small signs of wear, especially on the polished bezel, the case sides, and around the lugs.

There are no obvious large dents visible.

---

## Dial

The silver-colored dial has a subtle vertical satin finish, which provides an appealing contrast with the dark details.

The hours are indicated by applied rectangular hour markers. These markers have dark central portions that are framed by polished metal edges.

The large, open-worked hour and minute hands give the watch a distinctly sporty character. The hands include light-colored inserts to improve legibility.

Along the outer edge runs a detailed minute and second scale, with five-unit interval numbers.

The Carl F. Bucherer logo and brand name are located under the 12 o'clock position.

At the bottom of the dial is the inscription SWISS MADE.

---

## Big-date display

One of the most distinctive complications of this Patravi is the big-date display under the 12 o'clock position.

The date is shown via two adjacent windows. This allows the use of considerably larger numerals than a conventional date display.

The big date is a central part of the design and is particularly easy to read thanks to its prominent position directly under the brand name.

---

## Chronograph

The watch is equipped with an automatic chronograph with three separate registers.

At 3 o'clock: Small seconds hand for the regular time display.
At 9 o'clock: 30-minute chronograph counter.
At 6 o'clock: 12-hour chronograph counter.

The long central chronograph seconds hand is used to measure elapsed seconds when the chronograph is engaged.

The sub-dials feature concentric circle patterns and dark outer rings.

These details give the registers extra depth and help them clearly stand out from the silver main dial.

---

## Movement

The watch is powered by a Swiss automatic mechanical chronograph movement.

Type: Automatic mechanical
Frequency: 28,800 vph
Functions: Hours, minutes, small seconds, chronograph, and big date
Winding: Automatic via rotor

The movement is visible through the transparent case back.

The automatic rotor features extensive decorative finishing, including the Carl F. Bucherer emblem and gold-colored inscriptions.

Also various components of the underlying mechanical movement are visible through the transparent sapphire crystal case back.

---

## Timegrapher measurement

The timegrapher measurement yielded the following results:

Rate deviation: -5 seconds per day
Amplitude: 241°
beat error: 0.1 ms
Twilight angle: 52.0°
Frequency: 28,800 vph

These measurements reflect the performance of the movement during the performed test.

A timegrapher measurement is a snapshot of the movement's performance under the measured conditions. The measurement does not guarantee future accuracy or the mechanical maintenance state of the movement.

---

## Case back

The watch features a transparent case back, allowing the automatic movement to be visible.

The stainless steel outer ring is secured with multiple screws and features various engravings.

Reference: 11.0892
Water resistance: 50 m
Collection: PATRAVI

The transparent construction offers a clear view of the decorated rotor and various components of the mechanical movement.

The case back shows normal to clearly visible signs of use, including scratches and fine hairline marks on the polished stainless steel portions.

---

## Crown and chronograph pushers

On the right side of the case is a large, knurled crown.
Above and below the crown are two chronograph pushers.
These have an elongated shape with dark inserts, giving them a distinctly sportier look than the rest of the polished case.
The crown, chronograph pushers, and surrounding case portions show signs of wear that are consistent with the overall condition of the watch.

---

## Leather strap

The black leather strap shown in the photos has a crocodile pattern and contrasting light-colored stitching.
The current band is clearly worn and shows signs of wear, bending, and deterioration around the adjusters and in places regularly exposed to use.
The leather strap will be replaced before sale.

---

## Clasp

The original Carl F. Bucherer folding clasp remains.
The stainless steel clasp is marked with:
- Carl F. Bucherer
- Carl F. Bucherer emblem
The clasp shows clearly visible superficial scratches and signs of wear, but the engravings remain legible.

---

## Wrist size

With the strap shown in the photos, the current fit is suitable for a wrist circumference of approximately 18 to 19 cm.
Since the leather strap is being replaced, the final suitable wrist size will depend on the replacement strap mounted before sale.

## Water resistance

The original model specification is 5 bar / 50 meters.
For a used mechanical watch, the current water resistance cannot be guaranteed without a recent pressure test.
It is recommended to have the watch tested for water resistance before exposure to water.

## Overall assessment

This Carl F. Bucherer Patravi 11.0892 is in good but clearly used condition.
The 40 mm stainless steel case shows scratches, fine micro-scratches, and other normal signs of wear, particularly on the high-gloss polished surfaces.
The silver-colored dial presents itself neatly and stands out with the prominent big-date display, three chronograph registers, applied hour indices, and striking open-worked hands.
The combination of a big-date complication and an automatic chronograph gives this Patravi a particularly technical character.
The automatic movement, with a decorated Carl F. Bucherer rotor, is visible through the transparent case back.
During the performed timegrapher measurement, the watch recorded a rate deviation of -5 seconds per day, an amplitude of 241°, and a beat error of 0.1 ms.
