Moonphase – The First Timekeeper


Slim Line Classic – Easy to wear

The very first time measuring instruments were based on the phases of the moon. Historically the phase of the moon has been important in farming for sowing and harvesting, in fishing when the optimal catch is on a full moon and in many religious festivals.

Our customers say...

“Dearest Mark;

Just a quick note to advise you that the Claude Bernier Double Heart Limited Edition you worked so hard to arrange for me went over Fabulously on Christmas day... Literally, she cried tears of joy over it and had totally forgotten about discussing it way back in the summer. Thanks so very much for all your efforts, and you'll be pleased to know it is now prominently on her wrist when we go on any evening outings, and has moved up to the #1 spot in her watch case... ( she has 8 timepieces now). It will be traveling to Aruba with us this weekend for 10 days in the Caribbean...she's completely enamoured with it.

Again... Thank-you so Very much... and we will definitely be doing business again

“First off, these watches are incredible and last a lifetime!

They are affordable for a Swiss made watch. This website offers fantastic service! After I ordered my watch strap,

I received an email thanking me for my purchase and letting me know my order was submitted.

It wasn't an automated response either since I replied to it! I was shocked at how quickly I received my watch strap as well!

I 100% recommended buying a Claude Bernard watch from this site due to the impeccable service they offer!


Wilson  Cheltenham


“Thanks for all your help and outstanding service!

Hope we can have another transaction in the near future with a timepiece for me.... take good care!  Cheers! “

"Wow! I am impressed by your customer service! 

Thank you!"

Lynn Friedman

"I can safely say I'm delighted with my new Claude Bernard watch. I was choosing between this and a Mondaine and so pleased I went with this now. The service received was great - the 1st watch I ordered turned out not to be my style, so spoke to Mark who gave good advice with no quibbles about doing an exchange and got the right watch at 2nd attempt. Service was quick and efficient. Very happy customer."

Mike - Oxford

"I have received excellent customer service from Mark ! Really second to none, my calls or emails requesting order updates or information about my watch were replied promptly and he displayed great knowledge in the subject matter.

My watch is an absolute show stopper and couldn’t be more pleased with it !”

Shaun - Epson

“The after-sales service by Claude Bernard has been excellent; prompt, courteous and efficient. I am the proud owner of one of their automatic watches, which are beautiful instruments.”

Mr Andrew Judge - Cheltenham
