Good thing it comes with a 2 year warranty,
because your going to need it. I have this same Mondaine watch with a different band that I have paid to send back to Switzerland factory 4 times in the past 2 years. I am still waiting for them (2 months) to send me another "new" one, so I bought a different finish Big Date watch in the mean time. BUT it also had problems with the date window being unreliable, after setting the date, the date would not advance for 26-36 hours so the date is always 1 day or 2 days behind after initially setting it. You will have to reset the date at the end of EVERY month as well because each individual date dial has 10 digits. Also the lens will fog up when exposed to direct sunlight after about 2 weeks. I have another Mondaine watch that doesn't do that, and my wife has this watch in a woman's model that works great.
After getting 4 bad watches from the factory, and then having the 5th one fail with the same date problem, Mondaine factory said "send us the watch to our service center and we will send you a new one." The factor in Switzerland uses cheap foreign made parts so they can keep sending you "new" ones.
Swiss made but is it really Made in Switzerland??
As for functionality the watch is easy to read, Big Date & Night Vision glow is the BEST, it's the only things that keeps me coming back for more punishment.
I love the watch design , but can't stand reliability issues.
