Question –  What do these watches have in common?

Radio Control 1991-2009

Radio Control watches from 1991-2009

Answer – Radio Control and split second accuracy!

Although it’s been around since the mid ’80’s, Radio Control on clocks and watches is still very much in the minority.

There are plenty out there of course, but rather like 4 wheel drive cars – you know – safer, better traction in poor road conditions and reasonably priced, they haven’t taken the world by storm.

And it’s the same for the Radio controlled watch. It too has many advantages, all good, but not universally accepted.

It does beg the question – why? and what ARE the advantages of Radio Control.

Note – top left is the Junghans Mega 1, the first RC watch, others are Casio, Oceanus, Citizen, Dugena, Regent, Skagen, Kienzle and others.

Well first off – your watch always shows the right time. The watch receives the correct time from atomic clocks – so you have the  most precise watch in the world.  No setting, no resetting and always on time….which is arguably the most important requirement for any watch, surely.
Then the  watch movement doesn’t have to be  expensive high-end quartz – I mean around + or – 15secs a month should do it.  So it can be low to mid priced and affordable.
What else?
Well it makes World Timers for once a really practical proposition – no worries about moving the time forward or back and being slightly out – because it’s never “out”. Just set your zone and it automatically moves to the “correct” time, every time.  And DST or Daylight Saving Time……forget it – that’s done automatically for you every time, so no missing that appointment!

So where are these Atomic Clocks, how accurate are they and how do they control your watch?

Well it’s all pretty simple as far as we are concerned. Various countries across the world have these marvelous caesium clocks (Atomic Clocks).  The ones that are accurate to a second in 20 million years sort of clock.
These in turn send their time signal to a transmitter and it is received by your watch……There – I said it was easy!

Where are the clocks –

In Germany, the official time is established in the Physkalisch-Technische Bundesanstalt in Braunschweig the national
meteorology institute.
In Great Britain, the National Physical Laboratory in Teddington near London is in charge of their clock.
In the USA, the responsibility falls to the National Institute for Standards and Technology (NIST) at Fort Collins in Colorado.
In Japan, it’s the responsibility of the Communications Research Laboratory (CRL) in Tokyo.

How –

The time calculated by these atomic clocks is first sent to radio towers.
In Germany the transmitter is in Mainflingen near Frankfurt.
In the UK there is one in Anthorn in Cumbria, England.
In the USA it’s located in Fort Collins in Colorado.
In Japan it’s in the Otakadoya mountains in the North East and Hagane in the South West.
The German radio tower in Mainflingen for example has a range of up to 1,500 km & covers most of mainland Europe.

Today the Atomic clock transmitting stations have a quite incredible range.

Here in the UK we’re also spoilt for choice.  Depending on the watch model we can pick up the transmitter in Cumbria  (it moved from Rugby in 2002)  or from Frankfurt in Germany, which is over 700 miles away (I live in Scotland).

In the USA their transmissions are even more powerful at a 1500 miles radius or more.

The graphic on the right here shows their respective ranges and rough locations….

Today there are watch models that have pretty much world cover. In some models they have as many as 5  tiny built-in receivers.  Those models will pick up the Atomic signals from all the locations shown on the map here –  the USA, UK, Europe and Japan – and incredibly these watches are still  relatively inexpensive!

Just as an example the Casio watch shown here in the first small image is a 5 receiver model and quite  inexpensive at around £30.00

They can also be highly sophisticated – here is another Casio – an Oceanus Manta 5 receiver model. Somewhat more expensive perhaps but with Solar Power in addition to RC, Chronograph and Timer functions and a very high quality build, it shows the wide variation in styles available today –

Like some of the more expensive Oceanus and Citizen Attesa models, these tend to be marketed and sold in Japan only, though with the internet of course, now available to all.
The Oceanus shown here is an all analogue Radio Controlled watch and like others of this type, attempts to synchronise (get a signal) at night, say at 1am.  If successful OK, if not it tries again at 2am then 3am and normally takes around 2 minutes.
This model is also a World Timer and has a Titanium case and bracelet and for an RC watch is very neat at only 8mm thickness.

Of course Radio Controlled watches are not the sole preserve these days of the Japanese, there are many others, such as Junghans of course as the originator of the first Mega 1 – this is their latest version – the Mega 1000 –

With this watch they hark back to the days of the first Mega 1, with it’s digital presentation, but with superb clarity and the very latest in radio reception movements. Junghans have a wide range of more traditional Radio Controlled watches and again for this technology are not expensive.

And let’s not forget dress watches – they too can be Radio Controlled –
This one is a Dugena, a rather stylish German designed and manufactured watch complete with Radio Control, with a digital calendar display, auto DST and a signal call on demand feature. So there are plenty designs and styles to choose from.

So back to the question.

Why is it that this fabulous watch technology isn’t more widely accepted?
I mean not only do you get Radio Control now but it is often accompanied by so many other upmarket features.
Solar Power (no battery changing), World Timer (with RC this really comes into it’s own) plus chronographs & timers features, alarms, Titanium, Water Resistance, anti-reflective coatings, scratch resistant this and that……the list goes on.
There are lots of styles available now such as divers, aviators, minimalist or dress and surely are becoming the ultimate watch…..so what’s the problem?

Well I suppose it’s us again…..people….and our likes and dislikes and of course that peculiar place that a watch has in our affections.
It’s really very personal…..

I mean – clockwork people are not in the least interested – those of us who love the mechanics of a watch, the quality of miniature wheels and cogs all working in harmony to create a measure of – time.  A work of art even.
They don’t care a jot if it’s a few seconds out in a day or a week! – it’s close enough – we’re not computers anyway!

And there are  many others.  I mean and I’ve heard it said – do we NEED to be so accurate?

Do we really need 4 wheel drive when it only snows for maybe a week each year and when do we ever go off-road?

Well maybe not often I suppose, but it’s nice to have the choice and maybe that’s what it’s all about. Yes we have innovation, new technology and so on and good that we have it otherwise we’d stagnate. But we also have tradition and elegance and craftsmanship and beauty.

Watches may be about time, but in a way are somehow timeless – so as long as the price is right, why not have both!

Attesa – the ultimate watch?

The ultimate watch?

I took possession of this just the other week and it has NOT been off my wrist since – What a watch!
My biggest surprise was when I opened the box –

Whilst listed as around 42mm diameter (ex crown), this has none of the elegance of my previous Oceanus Manta – It is one very SOLID piece of kit!  Maybe the lug to lug measurement could be an issue for small wrists? – We’ll see.
However this model is incredibly clear to read despite a quite busy dial, the big broad luminous hands so easy to see against the black dial.

With double AR and not much on the dial that’s actually reflective anyway, it is very, very impressive.
Unlike my Navihawk this model has a centre seconds hand which I personally have always preferred. It doubles as a Radio signal pointer to indicate signal strength and receive confirmation.
A Charge level display @10 shows the secondary battery state and I note it points to the centre of each level, so level 3 is fully charged, which is around 130 to 180 days. Also at the same location on the dial is an indicator which shows which transmitter the watch is using – this is location dependent on the setting youv’e keyed in as your Home etc.
UTC displays permanently @12 and the mode selector is @6 and is operated by pulling out the crown 1 click and rotating left or right.

World time – Simply set your home town, which will show in the  display @9, press a button and the hands immediately move to your own time. The previous hands time then jumps to the digital display. It has 43 cities built in to the programme and you can also manually set odd Time Zones or a new city.

Dial detail

Dial detail – packed but superb broad analog hands stand out clear

The case is really solid and does away with the ever larger slide rule bezels that virtually no-one uses – the watch is much cleaner as a result. The plain bezel is actually coloured a dark brown, but as the image here shows, it’s really quite subtle. The two pushers either side of the crown are also brown.
The crystal is outstanding with probably the best double AR I’ve seen. It is very clear under any lighting situation and the dial information is clearly laid out.
There is also a rather cool LED orange glow light feature available to illuminate the digital displays if needed. And the hands and numerals have an improved lume – certainly much improved from my old Navihawk.
This model also has a full auto Calendar (with Daylight savings times), 24hr 1/100sec Chronograph, 99 minute Timer and two individual Alarms that can be set in world time or Home time.

It also has a nice broad bracelet – starting at 24mm and tapering to around 20mm at the clasp, which features a slider adjustment for when you’ve had too large a dinner!

Fits even a small 6.7" wrist

Fits even a small 6.7″ wrist – just . . .

Whilst it looks neat even on my smallish wrist at 6.7″ – it is deceptive being nearly 54mm lug to lug (and this might be a problem as the main case extends past the normal line of the lugs and almost into the strap profile) and is about as big I as would want to take (42mm diameter and 12.6mm height) – but it sits neatly enough, just, and the fact it’s Titanium means that after a minute you don’t even know it’s there!

Finally – the Radio Control – This watch due to my UK location, picks up the DCF  77.5kHz signal from Mainflingen, near Frankfurt/Main in Germany and I live 700 miles from the transmitter. It picks up the signal every time, usually at high strength (H) and synchs in around 2 minutes. I don’t even take the watch off and I’m one restless sleeper….! (Note the watch has 5 receivers (US, Europe, China and Japan).

So one of the most practical watches around for my money – Solar powered, absolute RC accuracy, World Time easily set, Chrono, Timers, scratch proof Titanium with the Duratec coating and the clearest crystal I’ve seen………

So…What’s the downside, the faults and the points I maybe don’t like?

That’s easy to answer – NONE

Quite simply for me this could be the Ultimate

I love it!

Update February 2015  – However after some years I found I was not wearing this model – why?   The answer to that was I suppose the fact that after wearing and owning it for some time I realized the lug to lug dimension was in practice just too big for my smallish wrist.  It over overhung the wrist and couldn’t wrap around the wrist and to change the bracelet for a strap wasn’t really an option.   The case shape and the non standard bracelet fixing didn’t lend itself to change.  So as my mantra at that time was – if I don’t wear them – they go . . .  simple as that.    Hey Ho!  😉
