Simply a beautiful watch

Looked at many on the website. Really liked the simple but elegant look of the Calendrier watch with the blue dial. Got set up pretty easily and have enjoyed ever since. Very happy with purchase.

My newest and dressy-est Citizen

Great watch with lots of sparkle. The excellent bracelet is comfortable, intricately detailed, and sparkles like jewelry. Cool enough for work and fancy enough for a night out with the ladies. Sporty enough for the tennis club, so it's too bad I don't play tennis. The blue face is nice and is darker in person than it is on the website...FYI.

Daily wear stunner

This watch caught my eye with the blue. It looks stunning in person and especially in sunlight. I have worn this watch daily for a year and I still catch myself just staring at it. I'm a handyman and it takes a beating but still shines up nice!

In Love

My wife got me this watch for our anniversary. As soon as I laid eyes upon it I was mesmerized. Blue is actually my least favorite color, but this watch is so beautiful; the way the light bounces off of it and it never has a glare. I HIGHLY recommend any watch lover, liker or enthusiasts to go get this watch. It is crafted to perfection and it is an eye catcher and a convo starter. I love it, worth every dollar.

Stunning

The blue Calandrier watch face is beautiful and catches a lot of light. It's a darker blue than I thought, which is good because it'll match most blue clothing and NATO straps. For the money this was an easy pull and I'm glad I bought it.
