The upside is that this does not really interfere with viewing the dial as the hands and markers are most always visible despite the light reflecting on the crystal. Next is an issue with the tools provided with the breitling replica chronometre navitimer watches. The bracelet requires special tools because each screw in the bracelet that holds the links together is double sided. This means that you need to hold one end of the screw bar to unscrew it from the other. CX throws in a high quality Swiss Bergeon 2mm screw driver with the watch, but that alone isn't enough to adjust the bracelet. Meaning that you need an extra tool to complete the job. Given that you have metal bracelet or rubber strap option, it would have been helpful for CX to supply a full strap changing kit. Having said that, this watch is nothing less than a professional instrument. It is a worthy investment to get the parts needed to change the strap if you have the skill to do so. I have the tools and was able to do it just fine. Otherwise, if you aren't skilled with screw bar strap changes or bracelet adjustments, I do recommend taking the breitling replica digital series watches to someone who can do it.
Many of you are very concerned with having high quality levels of luminant in their watches, while diving or otherwise. The 20,000 Feet Diver is very visible in the dark. This does not really extend to the chronograph (aside from the lume tip on the chronograph seconds hand), but the hands for the time and the numerals on the bezel are all coated with thick, wide amounts of SuperLumiNova. The darkness viewing on a watch like this is on par with what you would expect from a professional instrument.No watch is perfect and if I had to find any quips with the breitling replica longitude chronograph watches I would mention two things. First is with the sapphire crystal, and it is merely a side effect of the intense curvature of the crystal done for its pressure resistance. While curved crystals are stronger, they also reflect more light. This crystal reflect a lot of light which give means that despite a lot of anti-reflective coating on the dial, there is still a healthy amount of glare.
