# How can you tell a real Accutron spaceview?

## How can you tell a real Accutron spaceview?

It is held in place by the crystal, which has a thin metal compression ring inside its rim. Factory spaceviews usually have white hands (in various styles and with a luminous insert) and white, orange or red sweep second hand. This is so they can be seen more easily against the darker colors of the movement.

## How accurate is an Accutron?

The Accutron’s movement was claimed to be accurate to around one minute per month, or two seconds per day — leaving mechanical movements in the dust.

How much are Accutrons?

They start at \$3,000 for the Spaceview DNA in black and gold, and top out at \$4,000 for the limited edition. These are fairly large watches – the Spaceview 2020 watches are 43.50mm in diameter, and the DNA watches, 45.10mm; case thickness is 15.40mm.

### What does Accutron mean?

ACCUracy through ElecTRONic
ACCUTRON stands for “ACCUracy through ElecTRONic”. The world’s first electronic watch functions with a tuning fork; a small fork-shaped piece that until then had only been used in music. Engineer Max Hetzel developed its transistor movement, which was able to achieve an unprecedented precision of a minute per month.

### How does Bulova Accutron spaceview work?

The “Bulova Accutron” has a frequency of 360 oscillations per second (360 Hz). The vibration of the tuning fork is controlled by a transistorized circuit in the following way: when the left magnet on the tuning fork moves to the right, the phase-sensing coil generates an induction voltage on the base of the transistor.

What do the numbers on the back of a Bulova watch mean?

The letter indicates the decade, while the number indicates the year within the decade. The decade codes are as follows: L = 1950s, M = 1960s, N = 1970s, P = 1980s, T = 1990s. For example, if your watch is stamped with the code M8, this means your watch was produced in 1968.

## How can I tell the age of my Bulova watch?

These codes are usually found on the backcase, but some can be found on the inside movement near the set-screw.

1. The first digit of the code corresponds to the decade.
2. The decade codes are as follows:
3. The second digit of the code matches the ending digit of the year in which the watch was manufactured.
