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.
