Bulova Black and Gold Accutron 2303 Mini

The World's Tiniest Tuning Fork Movement


This 1975 Accutron uses the the smallest tuning fork movement ever made, the 2303, which is only 19mm across! The "Mini Accutron" movement was introduced in 1971 and was intended for use in ladies watches although they were also used in men's watches, often with spacers to allow a larger case. Because of its small size, the tuning fork arms are much shorter and therefore resonate at a higher frequency than a standard Accutron - 480Hz instead of 360Hz.


This Mini Accutron is in NOS condition and even includes its original case.

Case: Excellent.
NOS, Mint.

Face / Hands: Excellent.
NOS, Mint.

Crystal: Excellent.
NOS, Mint.

Band / Bracelet: Very good.
The leather band on this Accutron is a modern replacement. It came with its original Corfam band, but I replaced it with a leather one. Corfam was considered a space age material in the late 1960s and early 1970s, however, it feels like plastic and never sold very well and was soon abandoned for use in wristwatches.

Function / Accuracy: Excellent.
This little hummer runs and sets properly and keeps Accutron quality time.
