Don’t let the Bells end

As a fan of the Seiko Bell-Matic, I came across this at a watch fair and really fell for it. I’ve never had a Citizen watch before – they’re another major Japanese brand that firmly established their own way of doing things and were notable in various firsts in the watchmaking world.

I discovered the premium site for knowledge of Citizen on the web – VCW. Have a look if you’re interested…


Anyway, this particular watch is from March 1969 and has a definite Rolex DateJust vibe going on, with the “cyclops” date magnifier on the crystal and the fluted bezel. For its era, it’s quite a big watch – 41mm case size when many others were in the mid-30s – and since it isn’t an automatic, it’s relatively thin too.


The defining characteristic is the dual crowns – the lower of which operates like a normal hand-wound watch; you wind it up (and it has about a 2-day power reserve) and pull the crown out to set the time. Changing date is a matter of winding the hands past midnight, but if you go back to before 10pm and forward again, it jumps another day so not as tedious as some, if the watch has been left still for a while.

20190407_175601The upper crown is wound to add power to the alarm spring, and pulled out to set the time that the little black arrow points to – this is the time the alarm goes off. Leave the crown pulled out and the alarm is then active, so when the watch reaches that time, either on its own or by advancing the hands, it will ring the alarm.

The movement is a Citizen calibre 3102, itself based on a well-used AS (A Schild) 1475 Swiss watch movement that found itself in all sorts of Russian Poljots and other watches of the late 1960s. It is quite probably the most-used alarm watch calibre, with about 750,000 watches sold using it – though Citizen’s variant would be less common, even though it was in production for around 10 years from 1964.

Unencumbered by the swinging rotor of an automatic watch, here it is in all its, er, glory?



The case back is quite interesting – it’s a press-on job and can only fit one way, helpfully guided by a little stud on the case. This is because there’s a pin on the back of the case back which the alarm hammer strikes, meaning the alarm is actually quite loud and the back of the watch vibrates – only those with the sleep of the dead would not wake up. The back side of the pin is visible to the lower right of the Citizen logo above.


Here’s a video of the alarm in action…

…. and what happens if you take the case off – see the hammer flying!

Seiko Bell-Matic #1

There’s something about Bell-Matics that I can’t help myself but collect and evangelise them. The basic premise is, in 1972 (say), if you wanted a watch which would remind you of something, there were no cheapie quartz things to fall back on… so you bought one of a variety of watches with a mechanical alarm. Seiko had a premium range called the Bell-Matic.

Introduced in Japan in 1966, but popularised outside in the early 1970s, these watches were produced until 1978/79. The timing movement itself is automatic, and the mechanism to ring the alarm is driven by a hand-wound spring – so to set the alarm, you pull the crown out one stop and rotate the outer bezel (with the red marker, in this instance) to point to the time you want the alarm to ring. Push the crown back in, wind it and then pull out the alarm button at the top.

Here’s a video of it doing its thing…

This particular watch was a lucky find – described in an auction as “with box and some papers”, it came with everything including the original till receipt – clearly a cherished item, sold by Catisfield Jewellery Store, 24 Catisfield Lane, Fareham, on 11th/12th April 1975 for £46.80. A special birthday present for someone, maybe?

It’s hardly been worn, this watch – maybe someone kept all the paperwork and didn’t like the watch much so didn’t wear it… or they liked it too much to wear it often, who knows…

Although it was sold in 1975, it was produced in October 1972 so may have sat on the shelf for a while in the jewellers.

Here’s an entry from the catalogue, supposedly 1973…

Why is this post entitled, “Bell-Matic #1”? Well, there’s more than one of them…
