Good quality clasp

I bought this clasp to pair with my new Raven, Airfield. I coupled the clasp with a black Hirsch Retro Ranger strap. I took a chance ordering as Flaco suggest that this clasp fits straps up to 3.5 mm thick. The Hirsch strap I chose is 3.8 mm thick. Regardless, the the fit was perfect. Also, the build quality on this German manufactured clasp is excellent and the aesthetics match my new watch and strap perfectly. Now about Holben’s: what an excellent company. Knowledgeable and customer oriented. I am very satisfied with the service I’ve received and will be a return customer. Mike has graciously answered any questions I’ve had and has gone above and beyond concerning my most recent purchase. I am very satisfied.

Fluco Deployant Clasp on my Omega Snoopy

I upgraded my strap on my Omega Snoopy and boy, does it make a difference. Much better than the pin buckle! It saves wear on the OEM strap and gets compliments. Much better than the cheap ones on Amazon.

Butterfly Deployant Buckle for my Omega Snoopy.

The Omega Snoopy comes with a pin buckle, not worthy of the watch. I searched around for a high quality deployant clasp and found Fluco. It is so much better than the ones on Amazon. It saves the OEM strap for unnecessary wear. Very pleased.


Love this thing. If it came in more varieties such as brushed steel or a brush and polish combo, I would definitely order more.

Great Bit Of Kit

My first deployant clasp for a strap. It’s really well built. Solid snaps where it needs to be. Fits my Hirsch Aryton brilliantly. Big thanks to Mike for testing it with my strap before I purchased. I am tempted to try to make a new hole cos I tend to sit between two sizes. But it is still breaking in and we’ll see if I do. Either way…quite satisfied. Also…extremely fast shipping!
