I am very happy with this watch, it is beautiful and runs great on time.

PERFEKT!

Återigen utan logga och så clean. Den här klockan är jag mest nöjd med. Tyngden, länken samt designen. Allt är verkligen bra här och ångrar lite att jag inte beställde flera olika design/färger i just denna modell. Mycket klocka för pengarna!

Got the wrong watch. Sending it back in return. Good quality.

I love it

One of my fav. ! I love it ✨

very good

very very good

Tolle Uhr zum fairen Preis

Auch ich war am Anfang etwas skeptisch und war mir nicht sicher ob ich mir hier eine Uhr bestellen soll. Habe es dann gewagt und wurde nicht enttäuscht. Die Uhr an sich hat eine super Qualität und das Laufwerk läuft bis jetzt einwandfrei. Nur die Lieferung hat bei mir ca. 2 Wochen gedauert. Ansonsten bin ich happy mit der Uhr und werde mir wahrscheinlich noch ein Modell bestellen.

Good design and style just like the photo, although the box is a bit damaged. Pack it better, but I'll overlook it because it wasn't much.
