A Tricky Problem to Solve….

It’s all well and good acquiring a nice, and rare, high end automatic:


….but what if it is no longer an automatic?! A completely worn out rotor thread left the rotor detached:


I am no watchmaker, so there’s nothing I could do about this; but I know a man who can 😉

This is a quick trailer for a post on how master watchmaker Brian Leiser (aka 31 jewels) fixed my Leopard Highness. Watch this space 🙂

Hisonic…A Boxed Set

Having a good vintage watch is one thing (a good thing of course 🙂 ), but having some of the ephemera that go with it makes it a little more special. Not least because by their nature ephemera are things that were used only in the relatively short term and were not designed to last a long time, so they can be hard to find…..here’s an example:



Inside the Cover: SONY DSC

And the watch in its place:SONY DSC

The box is hinged so the watch can be displayed:SONY DSC

The original cloth: SONY DSC

And the instruction / guarantee booklet: SONY DSCSONY DSCSONY DSC

Finally the leather strap and buckle:SONY DSC

Citizen’s Case Material Codes

I’ve just added – finally! – a new page listing all the case material codes that Citizen used up to the late 1970s. It’s as comprehensive as I can make it, but there may be more codes out there, which I can add of course if they can be verified. Some of the codes are obscure and very rare – I’ve not ever seen quite a number of them. It looks like some were used for only a short while when new materials were first used. For example ‘TI’ was used for cases and bezels made from titanium carbide, but this was replaced fairly quickly by ‘UHA’ – Ultra Hard Alloy. Maybe this was to avoid any confusion between ‘TI’ and Titanium, which was first used in 1970.

As always, comments and additional information are very welcome 🙂

Here’s a quick link to the page: https://sweep-hand.org/citizen-case-material-codes-used-on-vintage-models-to-c-1980/

My Most Accurate Timepiece…..

…….is this wall clock, made in the late 1960s I believe:


The Rhythm company became affiliated to Citizen in the mid 1950s, and clocks and some watches continued to be made using that name. This 30 day pendulum clock requires very little adjustment, typically about 30 seconds when being wound so only 1 second or so per day, which isn’t bad for a 50 year old piece.  The day date feature is great, as is the power reserve indicator which scrolls from right to left until it is completely red to indicate that winding in required. It also strikes on the hour and half hour, but the bell is pleasantly soft so it can be running all the time without disturbing the whole house!

The 67-9071 Chronograph Dials – Close Up & Personal

With many thanks to ‘Marty’, who sent me excellent macro shots, I’ve got some pics to share….and a question or two to ask 🙂  First though, which watch are we looking at? It’s the 67-9071 model from the 1970s fly-back chronograph range, i.e. with the 8110A twin register movement. Sometimes referred to as a ‘monaco’ in style, the lower case is black coated alloy, with an angular steel  upper case. It’s not too common a watch, and to find one in good condition is difficult – mine is not so good, so Marty’s images of his two examples are very useful and welcome in exploring the finer detail. The 67-9071 came with two primary dial colours, green and gold. This is Marty’s green example:


And this is the gold version (not Marty’s):


There was also a gold version with white lettering – this is from a 1974 catalog so definition is not great – it’s hard to see colours on the sub-dials for example, but a great reference for the original strap:


So let’s take a closer look. First the green dial – the textured finish on the main dial and sub-dials is nicely shown, with crisp printing:67-9071green3_zpszmsjmvsa

….and a clear dial code:67-9071green2_zpsmg6ijubr

When we look at the gold dialled example, we get to the questions:67-9071gold4_zps0a9if0zk

The printing is not quite as fine, and there is a slight gap in ‘chrono graph’ – that style can be found at least on one of the 8100 models though. Many of the finish and colours look very good, but there is less texture on the dial and sub-dials. 67-9071gold1_zpsh8llrzm6

Dial code looks good, but the font on the sub-dials is narrower than on the green one and gold reference example, and some of the numbers are positioned slightly further away from the sub-dial track: 67-9071gold2_zpskxjuewxy


I have seen the exact same dial on another model, sold as ‘mint and original’:67-9071mintampstrap_zpsl6xa8st8

Well, it’s not mint, and either the applied Citizen logo or the printing looks to be slightly out of line, but is it original?  Marty and I have considered this issue, and at the moment we think it is more likely to be after market, but we’d like to hear from others, especially if you are an owner of one of these. What do you think……?

Don’t have the shirt anymore….

….but I still have the watch 🙂


This is the 67-9038 from Citizen’s 1970s range of fly-back chronographs. Hard to find in good condition, got to be careful with this one:
