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.
