There are thousands of watch models on the market today. So why choose an Orient Automatic Power Reserve?

All Orient watches are known for their:

  1. Quality in-house movements
  2. Affordable luxury
  3. Power reserve indicators

This article will discuss the third feature, the power reserve indicator. Once called the Réserve de Marche, one watch aficionado described the power reserve indicator as the most useful feature on a watch other than telling time.

A (Very) Brief History of Power Reserve Indicators

Power reserve indicators were first employed on marine chronometers. Later, they were used in the accurate Railroad grade pocket watches, and Montres Breguet created the first prototype of a wristwatch with a power reserve indicator in 1933.

15 years later, in 1948, Jaeger-LeCoultre introduced a power reserve indicator, making the company the first to market wristwatches with a power reserve indicator to the general public.

How Power Reserve Indicators Work

Basically, the power reserve indicator shows the tension on the mainspring at any particular moment.

When you wind the mainspring via the ratchet, a special train of gears connected to the ratchet moves an indicator across a dial. The teeth on the barrel are also connected to the same train. Therefore, as the mainspring’s unwinds, the gear train operates in reverse and moves the indicator hand in the opposite direction.

The amount of power in reserve can be indicated 1 of 3 ways:

  1. Needle or hand
  2. Revolving wheel, viewed through an aperture
  3. Linear indicator

Since a watch functions best when it is at least 30% wound, a power reserve indicator is exceptionally useful. You will always know if your watch is in the “green zone” of power, and therefore whether or not you can take your watch off.

Why an Orient Automatic Power Reserve?

If you’re in the market for a durable, classic timepiece, an Orient Automatic Power Reserve is the way to go.

The black face of Orient’s CFH01001B automatic watch features a 40-hour power reserve indicator. Located below the 12 o’clock, the indicator accurately counts down the energy is left in the mainspring. The simple yet elegant face with a semi-skeleton is also a perfect example of how the indicator can seamlessly fit into the look of a watch.
