Frequently Asked Questions
FAQs help you quickly find answers to important questions – from product details and care instructions to return policies. This saves you time and keeps you well-informed, so you can make purchasing decisions with confidence.
All FAQsWhere are the ribbons manufactured?
Each of our straps in the online shop is handcrafted in our small workshop in the Bavarian Forest.
How do I care for the leather strap?
Avoid prolonged contact with water, sweat, and direct sunlight. Use a special leather care cream occasionally to keep the leather supple and extend its lifespan.
Can every strap be equipped with a folding clasp? How do I order the right size? And can you install the folding clasp for me?
Any strap with a thickness of less than 4mm
can be fitted to a folding clasp. To order the correct size of
folding clasp, the taper of the strap—i.e., the second number—is important.
If the strap is, for example, 20/16mm in size,
you would need a 16mm folding clasp.
We can also fit the folding clasp for you immediately; simply include a note to that effect during the checkout process.
Are the leather straps hypoallergenic?
Our bracelets are made from natural materials that are generally well-tolerated. The inner sides are often lined with hypoallergenic leather.
What kind of leather are the watch straps made of?
Our watch straps are crafted from the highest quality leathers and sourced from the most renowned tanneries worldwide. We name most of them, although this is not always possible due to fear of imitators.
How long does a Fluco leather watch strap last?
Fluco watch straps last significantly longer than cheaper alternatives thanks to their high-quality craftsmanship and reinforcing inlay. With daily wear, it is recommended to replace the strap after about 2–3 years, but let's be honest:
Who wears the same watch with the same strap for three years? Accordingly, you will enjoy your Fluco watch strap for a long time before a replacement is even necessary.
Gutes und solides Armband, passt sehr gut zu meiner Uhr. Ist Anfangs noch ein bisschen steif, aber das ist normal bei Lederarmbändern
Sehr schön verarbeitetes Armband. Da es aus Leder ist, ist leider am Anfang ein wenig steif. Es gibt Uhrenarmbänder, die das nicht haben, aber die sind auch um einiges teurer und wahrscheinlich auch nicht wasserfest. Daher ist es für meine Certina DS Action ideal und passt auch noch optisch sehr gut zu der Uhr.
Tolle Qualität zu einem angemessenen Preis
Eins vorweg: der Armband passt farblich und der Struktur überragend zur AW-Ultra!
Tragekomfort ist gut.
Aber die Adapter rasten nicht 100% ein.
Die Dornschließe ist eher kantig und mit grobem Finish (auf den Fotos anders wargenommen), die Löcher eher klein und egal, wie man aufpasst, die Innenseite leidet.
Die Nähte eher grob.
Wahrscheinlich würde ich das Band nicht nochmal kaufen, zumindest nicht mit der Schließe
Sehr robust, hält einiges aus.
Lässt sich gut reinigen, keine Fleckenbildung.
Lässt sich gut reinigen, keine Fleckenbildung.
Schweißresistent, ideal für den Sommer.
Sehr haltbar, hält auch Wasser und Staub gut stand.
Elegant und modern, passt zu jeder Gelegenheit.
Hochwertiges Material, sehr empfehlenswert.
Super Qualität, die Schließe ist sehr stabil.
Man kann damit tatsächlich schwimmen
Ich habe das Nautilus Band beim letzten Besuch der Firma Damasko gesehen und war daher von der Qualität überzeugt.
Schnelle Lieferung, sofort einsatzbereit.
Optik und Materialanmutung sehr gut.
Nach ca einer Woche im Gebrauch: Momentan noch sehr steif beim einfädeln in Schließe und Schlaufen, ich hoffe das das Leder noch weicher wird. Tragegefühl sehr gut.
Super Qualität! Absolut zufrieden!
Sehr gute Qualität und Verarbeitung.
Passt gut und hat eine gute Qualität, trägt sich anfangs nur ein wenig steif.
Sehr gutes Uhrenarmband. Es ist - weil es aus Leder ist - etwas steif, aber damit hatte ich gerechnet. Es gibt zwar Armbänder aus Leder, die von Anfang an weich sind, aber die sind wesentlich teurer und nicht wasserfest.
Sehr gute Qualität und optisch wirklich schön.
This strap is nothing short of a masterpiece. From the moment I fitted it to my watch, it felt like I had given the watch an entirely new identity. The quality of the leather is outstanding, with a beautifully refined finish and a reassuringly solid feel. The water-resistant properties make it especially impressive for everyday wear, without sacrificing that premium leather appearance.
What surprised me most is how dramatically it transforms the watch. It doesn’t simply complement the case and dial — it takes the entire watch to the next level. Suddenly, a watch I already loved looked more sophisticated, more powerful, and somehow more distinguished.
There is almost something fantasy-like about it. The Nautilus feels as though it belongs on the wrist of a wandering knight, a northern lord, or a seasoned adventurer who has travelled through rain, forests and forgotten kingdoms. The leather has that perfect combination of elegance and rugged character — refined enough for a royal court, yet tough enough for the road beyond the castle walls.
The craftsmanship is exceptional. The stitching, texture, finishing and overall construction all give the impression of a strap made to last. It feels substantial without being bulky, comfortable without feeling fragile, and premium without becoming overly flashy.
If your watch is the sword, the Fluco Nautilus is the leather scabbard worthy of it.
An absolutely fantastic strap that has completely elevated the appearance and character of my watch. Excellent quality, excellent craftsmanship, and an incredible transformation on the wrist. Highly recommended!
Absolut Top!
Top! Super Verarbeitung.
Super Qualität
Ein optisch äußerst gelungenes Armband, das auch hinsichtlich seiner Verarbeitungsqualität voll überzeugen kann! Empfehlenswert!
