Review: 'Bentley Motors' Chronograph (30s)

Breitling Bentley 48mm 'Bentley Motors' Chronograph (30s)

With the distinctive Knurled Bezel that is a Bentley trademark, the watch does not go unnoticed, and the wide, shallow dial gives extremely easy reading with a bold statement.

BENTLEY MOTORS details

Movement

Breitling Calibre 25B, chronometer-certified by the COSC, selfwinding high-frequency (28,800 vibrations per hour), 38 jewels. 1/8th of a second chronograph, 30-second, 15-minute and 6-hour totalizers. Date.

Case

Steel or red gold. Water-resistant to 100 metres. Screw-locked crown. Rotating pinion bezel with variable tachometer (circular slide-rule). Cambered sapphire crystal, glareproofed both sides. Diameter:48.7mm.

It is a 30-SECOND CHRONOGRAPH

Inspired by a patent filed by the founder's son Gaston Breitling in 1926, the ingenious principle of the 30-second chronograph is distinguished by its central hand sweeping around the dial in half a minute instead of the customary 60 seconds. This original system, featured on the Bentley Motors, Bentley GMT and Bentley Mulliner Tourbillon models, ensures readings of the measured times accurate to within 1/8th of a second.

Variable tachometer

Most of the Breitling for Bentley chronographs are equipped with a variable tachometer, a world-exclusive feature by Breitling. When used in conjunction with the chronograph, this system enables one to measure the average speed, whatever the time elapsed, the distance covered or the speed reached. It thus features optimal operating efficiency in relation to standard tachometers which are limited to observations based on times of less than 60 seconds.

The variable tachometer consists of two scales: a fixed scale with hour/minute/seconds markers in the centre and a mobile scale around the outer rim. The fixed scale is read off clockwise and the mobile disc counterclockwise. The user may for instance take advantage of the chronograph functions to measure the time a vehicle takes to cover a given distance. The distance covered (outer scale) must always be placed opposite the marker serving as the reference basis for the calculation (hours, minutes or seconds on the inner ring).

To read off a result, one must ensure the decimal is correctly placed (since the figure 3.2 may represent 0.32, 3.2, 32, 320, etc.).

Example: A vehicle covers 50 km (or 50 miles) in 15 minutes. What is its average speed?

Solution: place the figure 5 (=50) on the mobile disc (distance covered) opposite the minutes marker on the fixed scale, and then read off the result opposite the figure 1.5 (=15) in this case 200 km/h or mph.In much the same way as a slide rule, the variable tachometer serves to perform many other operations: multiplications, divisions, rule of three calculations, hourly production rates, hourly output or consumption rates, heartbeats/minute (pulsometer), etc.

Conclusions.

  • Bezel with knurl is way inferior to genuine :nono:
  • Dial: Major fault is the layout of subdials and their numbering :nono:
  • Functions: the replica has an ordinary but great working Chronograph but certainly no 30s function :nono:
  • Built: the head, case and bracelet are solid enough and the watch feels heavy and big so that’s good :clap2:
  • Quality: Being an replica, the watch I bought was well built and the movement functioned superbly with excellent timekeeping. Chronograph works like a dream. :clap2:


    Advice:

    • Obviously this is not a replica worth buying if you want reasonable accuracy in terms of genuine details and functions. It is not an easy watch to replicate :nono:
    • But on the other hand it is not expensive and it is a powerful looking, solid and well made watch. So it is an excellent watch to start with if you want something big and complex looking. On its own it is a quality made and working piece and you may never meet an individual that knows what it really should look like and function (but you never know that for sure) :clap2:

But what always disturbed be was the spelling mistake on the case back...Swilzerland?

But who would ever spot that :euro:...even at this magnification its not so visible..and then these are probably made in Swilzerland :bangin:

Hmmmmm

Perhaps it looks better in real life, but on pics I am not so sure.

Just too much gold.

I does help when it is on a leather strap. But the gold bracelet is horrible. (Sorry to your freind ......... hopefully he is not reading the forum... ;) )
