Not sure if I missed some information: is it limited? Until when should we order?

I cannot wait! I am totally blown away by your hard work and dedication to create this masterpiece. Congratulations on your hard work and effort. All the best, Tony.

I have one question, is it a lateral or vertical clutch for the chronograph?

From Lebois & Co: " It uses an oscillating pinion, a simplified form of a vertical clutch derived from the ETA 7750 architecture ".

Great question!

Tony, we are very happy to have you in!

Very delicious dial, well done and thank you!!

Thanks for your support, mon ami.

Gorgeous! Great work! Thank you for making this happen!

Yes, we are many here to be mad about enamel dials. Donze is a reference, here.

Beautiful watch and wonderful attention to detail, including the blued conponents.

Merci beaucoup, xto.

Beautiful dial and hands, well done, Bravo!

Thanks, S!

"The navy calf strap and pin buckle complete a package that feels both vintage-inspired and thoroughly contemporary."

Straps are always such a personal taste thing .... I will buy an dark blue / navy croc strap.

Right but I asked because the pictures are showing brown while the write up says navy.

As far as I understand we get both, the navy and the brown

Fantastic, so beautifully conceived and executed 👍
