Hoe Today's Watches krijgen hun Glow

Eerder deze week brachten we u een historisch perspectief van de eeuw-lange reis naar luminescentie om de wijzerplaat te brengen voor een gemakkelijke 's nachts en onder water te lezen. Als we aan het einde van dat artikel worden genoemd: de favoriete materialen die worden gebruikt voor horloges is Super-LumiNova (zowat twee decennia geleden ontwikkeld in de vroege jaren 1990).
Super-LumiNova is niet-radioactief en is een strontiumaluminaat stof gemaakt in een groot aantal kleuren die het horloge cijfers, markers, handen en andere accenten dial in staat te gloeien blauw, groen of zelfs rood-oranje, afhankelijk van de gebruikte mengsels. In de loop der decennia is het materiaal gevorderd dankzij een veel onderzoek en ontwikkeling, en de Super-LumiNova van de vroege jaren 1990 is uitgegroeid tot een nieuwe intensiteit die ten minste het dubbele van de kracht van de vroege versies. Super-LumiNova kan oplopen tot 10 keer helderder dan de vorige zink- sulfide gebaseerde materialen, en wordt toegepast in verschillende sterktes.
Na het absorberen van voldoende UV-licht, de fosforescentie oplicht in het donker voor uren. De pigmenten, echter, moeten worden beschermd tegen contact met water of vocht, en dus zijn ze over het algemeen alleen gebruikt op de wijzerplaten (omdat ze beschermd worden door het kristal) en niet op bezels. Super-LumiNova is de huidige marktleider in lichtgevende wijzerplaten.
Er zijn echter ook andere materialen op de markt die een aantal van de professionele sport horlogemerken gebruikt voor duik- en piloot horloges. Top waaronder een tritium-apparaat genaamd "tritiumlichtbronnen lichtbron" (GTLS), waarbij het materiaal wordt ingekapseld in kleine glazen buisjes. Deze kleine buizen worden vervolgens met elkaar geplaatst om een ​​helderheid die maar liefst 10 keer helderder dan toegepast Super-LumiNova kan bieden.
MB-Microtec is een grote ontwikkelaar en leverancier van het minuscule buisjes systeem - het aanbieden van GTLS radioactieve luminescentie opgesloten in hermetisch afgesloten capsules. Opgemerkt wordt dat GTLS verboden in sommige landen ook al is ingekapseld in glazen buizen omdat het materiaal immers radioactief.
Wat is beter? Het kan niet dat een beter is dan de andere, maar dat in feite kan men langer mee dan andere. Zo is gevonden dat, terwijl Super-LumiNova begint te dimmen na ongeveer 20 minuten, zal tritium capsule niet gedimd gedurende 15 tot 20 jaar. Bovendien, terwijl Super-LumiNova moet worden blootgesteld aan een lichtbron om de

Attesa – the ultimate watch?

he Citizen Attesa ATV53-2833

Perfex Multi 3000, Solar powered Eco-drive (with 2.5yrs power save),Radio Controlled (US, Japan, Europe), Titanium (Druratec Ti), Double coated AR.

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 – 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 – 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!
Note 1 – Movement – Cal.No.U60
Note 2 – Perfex 3000 system features –
1 – JIS Type-1 anti-magnetic
2 – Impact detection system
3 – Hand correction function

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.

How to change the diesel watch battery?

Many diesel watches are powered through a small battery inside the watch that eventually wears down and needs to be replaced. Watch batteries can be purchased at most drug stores, grocery stores, hardware stores or watch repair stores. Replacing a watch battery takes a few steps and a few tools, and most watches will need to be set once the new battery is in place.

Instructions

1.Place the watch face-down on a soft surface, such as a towel or a computer mouse pad. Examine the back of the watch, which will either be smooth with a small indent on the side or have 4 to 6 small slots, which is called a screw back case.

2.Insert the flat blade of a small screwdriver, such as the one used for eyeglasses, at the small indent on the side of the watch if the case back is smooth. This is a snap back case.

3.Use the small screwdriver to turn the small slots on the back of a screw back case. Alternatively, insert the metal tips of a tool called a case back wrench, which can be purchased at watch repair stores, into the slots and turn the wrench to open the watch.

4.Lift open the case back. Remove the battery, which appears as a small, flat disc. If there is a clip holding the battery in place, use the blade of the screwdriver or your fingernail to lift open the clip to remove the battery.

5.Insert a new battery and replace the clip, if necessary.

6.Put the case back on the watch and use the screwdriver or case back wrench to turn the slots on a screw back case to their original position, closing the case back.

7.Line up the indent on a snap back case with the notch on the side of the watch and press firmly to close the case back.

8.turn the watch back over and gently pull out the small knob on the side of the watch (the crown) until you hear a click. For watches with calendar settings, pull the crown out until you hear two clicks.

9.Turn the crown clockwise until the correct time (hours, minutes) has been reached on the watch.

10.Push the crown back in to the side of the watch. Turn several times to wind the watch.
