Wunderschöne Uhr

Ich bin sehr froh, dass ich bei diesem Kickstarter-Projekt mitgemacht habe. Die Uhr ist wirklich sehr schön, super verarbeitet und meine neue Alltagsuhr. Ich habe sie am ersten Tag aufgezogen, nach der Atomuhr gestellt und nach 12 Tagen kontrolliert. Sie ging genau eine 1 Minute nach. Dies entspricht 5 Sekunden pro Tag und dieser Wert ist für eine mechanische Uhr in dieser Preisklasse einfach sehr sehr gut, um nicht zu sagen sensationell. Das Armband ist hervorragend verarbeitet und der Verschluss einfach schön.

Østersøen Himmelblå

Too happy to have received my Østersøen Himmelblå, I fell in love with it from day one, I waited anxiously for it and finally it's in my hands!!! An amazing watch, all my (high) expectations were met!!!

A true conversation piece

The Østersøen Himmelblå is just as stunning in the metal as on photos. I especially adore how the sky blue dial pops, and the convenience of the quick-change mechanism for both the bracelet and the FKM rubber straps. IMHO the orange FKM is the most fitting for a lively watch like this. I hope you will continue delivering amazing products, I will be on the lookout to see what comes next from you. Keep up the excellent work!

Amazing Finishing and Craftmanship

The finishing is superb for this price point. Hands and indexes look very sharp and harmonize with all other elements of the watch. The bracelet is excellent, as well as the optional Tropic rubber strap, above the average. Using for a couple of days, the watch is fast by only 1 second... showing that the Miyota 90S5 was well adjusted. Happy with the acquisition.

Eduard Suchánek

I am really surprise about the quality for the watch. Even the strap feels much better than competitive watches in the same price range. Also nice packaging, with nice box with cloth and screwdriver make the final touch.

100% recommend.
