Good looking and functional watch. Five stars!
It's functional, stylish and comfortable to wear. Easy to use. A bit heavy but quickly can get use to it. Made in Japan. Features, 6 band wave ceptor, perpetual calendar, sapphire glass, alarm,chrono, tachymeter, wr200. Brancelet can be adjust by removing full or half links for a better fit. Solar powered. 1 sunny day can provide energy for about 6 months. Looks posh too. I would buy again. Update 10.04.2020: After 2.5yrs i can surely say that this watch is really good choice. The solid link branceled put to the pouch to keep it in close to brand new condition and replaced by calf skin 24mm strap. I can feel the different as the watch lost its weight and gain the kind of vintage look [in my opinion anyway ;)] I forgot to mention at the first time that the luminous hand and dial are really nice blueish colour and lasts long too. Really happy of the purchase especially i see how much this watch costs now. Anyway it's still worth the money.

Amazing watch
This watch is beautiful. I bought it after my Accurist watch started to fall apart after 12 years of wearing it daily. I could easily have had it repaired but happened to see this in an airplane magazine and eventually decided to buy it. It arrived dead, but after about 2 hours under a bright light, it came to life. Easy to set the time, but of course you don't have to - just run a manual radio reception and it will update itself (I live in south east London and get a strong signal, from the tower in Germany). It also does this automatically at 2am every day, so whenever I compare it to the time on my laptop, or at the train station, it is always within half a second. Brilliant. I have relatively thin wrists and had four links removed, but that's no biggie. The only problems with this watch are: - Stopwatch doesn't show subseconds - Can't use a stopwatch immediately; you have to put it into Chrono mode first, then wait a few seconds for it to sort itself out The other advantages are: - it has an internal calendar with month and year* (*more precisely, it just know the number of years since the last leap year, which is good enough until the year 2100) - the hands and 12 markers glow in the dark - it looks really stylish

Great Watch!!!
Have waited a long time to treat myself to this watch. Now I finally have it am really pleased with it. Keeps perfect time, is very good quality and keeps perfect time to the second (with the speaking clock!). Is rfeally cool that it is radio controlled. It says in the instructions to put it on a window ledge or near the window to get a signal, I guess it will depend on where you are, but I put it away in a draw at night and it manages to update with a high or medium signal most nights! And as for the reviewer earlier that complained about the strap being to small, am confused by that, I am a man with not skinny wrists by any stretch of the imagination, and I have just had the strap made smaller to fit me more comfortably!! Finally a well done to Amazon and their delivery service, ordered it at about 20.45 in the evening paid for a next day evening delivery admittidley, but even so arrive by courier at 18.50 the next evening! impressed. If you are looking for a quality time piece that looks good and works well you could do a lot worse than buy one of these or any citizen watch to be honest.

Good and practical watch.
Looks great and feels good. Took a little bit to set up but that was down to having to wait for the battery to recharge, but once the battery was charged the instructions on the website where easy to follow.

Doesn't Keep Time Accurately.
Having experienced issues with Casio radio-controlled watches, where they routinely lost time and were not 100% accurate, I decided to switch to Citizen and chose this watch because it looked great and had excellent reviews. The principal reason for me buying this type of watch is that they are supposed to be accurate at all times and I hoped that Citizen would be better in this regard than Casio. It was a bonus that it was already accurate out of the box and so there was nothing for me to do other than adjust the bracelet to fit. The watch looks great and I love the fact that I will never have to worry about batteries ever again. At first the watch did exactly as it should and was totally in sync with the speaking clock. However, in time I noticed that it started to slip out of sync, sometimes by a few seconds, on other occasions by a few minutes. The only way to correct the watch to ensure that it was again accurate was to perform a manual adjustment, something I had switched to Citizen specifically to avoid, as this was exactly the same issue with Casio radio-controlled watches. This time slippage is now a regular occurrence and I have to perform a manual reset at least once a week, sometimes more frequently than this. As accurate time-keeping remains the most important feature of this, or any other, watch, I am hugely disappointed and would advise caution to anyone considering buying this item in order to have 100% accurate time-keeping. It simply does not deliver and the only difference between this watch and a radio-controlled Casio model is that it is much more expensive. Both are flawed in terms of accurate time keeping, so beware. I'll now have to wait for the release of the Apple iWatch in April to finally get a watch that keeps accurate time permanently without the need for manual intervention.

Grundsätzlich, um lästige und auf Dauer ins Geld gehende Batteriewechsel zu sparen, kaufe ich mir nur noch Funk-Solar-Uhren. Auf der Suche nach einem mir gefallenden entsprechenden Chrono bin ich auf die Citizen AT4004-52E gestoßen, welche mir optisch und hinsichtlich der Daten sehr zugesagt hat. Wichtig war mir hier (neben Funk und Solar) u. a. noch, dass die Uhr eine Alarmfunktion besitzt und nicht zu kleine Anzeigedarstellungen hat. Als hier bei AMAZON noch ein Top-Preis von 299,99 Euro gegeben war, habe ich mich zum Kauf entschieden. Dass es sich bei der Uhr um kein aktuelles Modell handelte, störte mich absolut nicht; mir war wichtig, dass der Chrono meinen Vorstellungen entsprach. Und meine Vorstellungen wurden in vollem Umfang erfüllt. Die Uhr ist groß, hochwertig verarbeitet und hinsichtlich der Funktion absolut einfach zu bedienen. Da brauche ich auch nach längerer Zeit kein erneutes Beschreibungsstudium. Es sollte einem jedoch vor einem Kauf klar sein, dass die Uhr, neben vier US-amerikanischen Städten, für Europa nur für London die funkgesteuerte Uhrzeit anzeigt - das war mir vorher schon bekannt. Für unter anderem die deutsche Zeit kann die Uhr jedoch auf der Funktion "A-TM" (Alternativzeit), jedoch ohne Funkfunktion, betrieben werden. Wer möchte, kann jedoch sehr einfach hin und wieder, beispielsweise über Nacht, auf die London-Zeit stellen, damit sich die Uhr zeitlich kalibriert. Anschließend einfach wieder zurück auf "A-TM" und gut. Eine Sommerzeit-Funktion ist für alle Zeitebenen ebenfalls vorhanden, welche bei "A-TM" auch sehr einfach und schnell umgestellt ist. Für die Band-Längenanpassung habe ich mir übrigens gleich bei AMAZON ein brauchbares und günstiges Uhrenwerkzeug-Set mitbestellt (Eventronic-147); damit kann ich jetzt auch den Batteriewechsel an meinen Nicht-Solar-Armbanduhren preisgünstig selbst durchführen.

Orologio molto bello con una forte eleganza e robustezza, in acciaio 316l con parte lucide a specchio e altre opache. In foto non si riesce a capire la bellezza e lucentezza. Cassa lucida con inserto in oro PVD con lancette e parte dei quadranti interni e lancette mini in oro con ottimo contrasto e facile lettura , grazie allo sfondo nero, ho altri 7 orologi e alcuni si fa fatica a intercettare le lancette ora e minuti. Pulsanti con marcata tolleranza in sede si ha moto gioco , ma non entra acqua. Bracciale senza interruzione dalle anse della cassa sembra un pezzo unico, senza gradini ma con continuità della cassa , proprio come piace a me, ci sono modelli che dalla cassa a cinturino ci sono stacchi dalla cassa con angoli di 90 gradi. Cinturino che segue una linea a sfinire con inserti longitudinali in oro lucido e acciaio satinato con bordo frontale acciaio a specchio ,mantenendo sempre lo stile della cassa, non ha la microregolazione ma ci sono 4 mezze maglie che è lastessa cosa. Fibbia di chiusura di facile aggancio basta fare una piccola pressione e scatta in automatico senza bisogno di insistere come nella maggioranza di orologi, cinturino ottimo. Orologio di grande vistosita specialmente al sole diventa brillante esaltando la sua presenza dominante al polso. Orologio di forte carattere e dominante ,proprio come piacciono a me, parlo da vero appassionato. Robusto e pesante nato proprio per dominare il tempo con la sua autorità. Orologio per il mercato inglese e radio controllato su Londra quindi in Italia sarebbe sempre indietro di 1 ora, però si può usare in modalità A-TM e impostando un ora di fuso per l Italia e tutto si mette apposto, ogni tanto se si vuole si passa su Londra e si fa una un sincronizzazione radio e poi si rimette su ATM mantenendo lo scarto impostato, comunque in 1 mese di utilizzo e sincronizzato il primo giorno , funzionando con il suo meccanismo al quarzo e rimasto sempre perfettamente sincronizzato al secondo, cosa che non mi succede con gli altri orologi che hanno sempre bisogno di piccoli aggiustamenti. Eco drive meccanismo con carica solare e risparmio energetico automatico, con una riserva di energia di svariati mesi al buio totale. Su internet si trovano istruzioni video e in pdf. AT 4004 52e Citizen a mio parere è un ottimo affare e un orologioda 1000 euro ,ma su Amazon si riesce a prendere con un forte sconto che ne vale la pena.

Este fue el reloj para mi boda y no pude acertar más! Queda genial e impone, además de saber que vas a tener un buen reloj para toda la vida. Tras una larga búsqueda intentando encontrar el reloj perfecto, lo conseguí. Estoy muy contento con él y le doy bastante uso. Sin duda, si me volviese a casar, lo volvería a escoger.

Ich liebe die Uhr. Etwas Einarbeitung nötig. Aber dafür bekommt man eine wirklich präzise und schöne Uhr. Zu beachten ist aber, es gibt keine deutsche Zeitzone, hierzulande muss man also die alternative Zeitzone verwenden. Finde ich aber nicht schlimm.

Come da titolo, niente di più bello. Per configurarlo non è stato per nulla facile, fino a quando ho trovato su YouTube un video perfetto. Non dovrete andare a cercare l'articolo che fa riferimento all'orologio in questione, bensì dovrete digitare questo: Citizen Eco-Drive AT4008-51E è esattamente lo stesso di quello che avete acquistato. Mi raccomando dovrete seguire esattamente l'ordine temporale indicato nel video. Dal reset ( importantissimo per il buon funzionamento) a seguire. Poi per la ricezione del segnale radio,esiste una applicazione che permette di ricevere il segnale radio attraverso gli altoparlanti del cellulare, (nome dell'applicazione è DCF77). GLI Altoparlanti dovranno essere posizionati di fronte all'orologio in corrispondenza del ricettore del segnale diverso per ogni orologio(viene indicato nelle caratteristiche del vostro dispositivo) Dovrete attendere che finisca di fare alcune operazioni (ci vorranno circa 10 o 18 minuti. L'importante è alzare al massimo il volume del cellulare, godetevi il vostro nuovo e fantastico Citizen. Spero di esserti stato utile. Ciaoooo
