remarks
At that time Omega "Speedmaster Quartz Ref.1860004" was sold in a wide variety of variations.
It bears the word "professional" which was not given to the automatic and date/day-date series.
Equipped with Cal.1620. Crystal watches at the time consumed more power than today's watches so a large-capacity thick button battery was required for operation. The problem is solved by using it and it is housed in a thin case.
Like the tuning fork type it was short-lived and no quartz model was made until the digital-analog X-33.
"Speedmaster Quartz Ref.1860004" is one of the few existing models and is now a very valuable model.
