Two-Year 9311 Review - Grade "A"
on June 2, 2007
I purchased this watch two years ago, after a full month of online research and jewelry store inspections of Submariner-style watches; specifically, Invicta Pro Diver models. By contacting the seller directly (via email) before purchasing, I was able to verify which model design was for sale. FYI - depending on the model year, the 9311 can have a red, gold or black/gold Inivcta logo on the face, the bezel can be coin-edged or scalloped, and the second hand may or may not have a gold logo at the base. My watch has a red logo and a scalloped bezel, and no second hand logo. Incidentally, that watch is marked 9311A on the watch back. The appearance of the watch is cleaner with the scalloped bezel, however, the bezel is a bit more difficult to turn, due to less grip. You will probably only turn the bezel four or five times a year, so its usability is not a critical feature. Also, The logo at the base of the second hand is clutter- I would recommend ordering yours without it.
Some pictures of this watch online portray the glow-in-the-dark indicator at the apex of the bezel to be a bright greenish dot- this is not the case on my watch. The indicator is not pure pearl white, but I wouldn't call it greenish, it is quite similar to the hour and hand markings.
One of the watch features that impressed me originally was the thickness and purity of the gold electroplate. I'm not a watchmaker nor a metallurgist, so I'm not sure what the ads that touted "23K gold electroplate, 7 microns thick" were really representing. What I can tell you is that after two years of at least weekly wear in all environments, (the office, outdoors, swimming, etc...) the gold color is still solid over all the plated parts of my watch. Even areas that have been scratched on the band are still golden.
Another concern of mine was the hardness of the crystal. Nothing ruins the appearance of a nice watch quicker than a scratched crystal. This model has a mineral crystal, not the harder sapphire type. Relax; after two years of indelicate usage, there are no visible scratches on its crystal. The only damage to my watch at this time (outside of incidental scratches on the band) is a scratch on the bezel that has removed some black paint (and replacement bezels are available).
The band has worked flawlessly, and the watch keeps very accurate time. I may adjust it a minute or two every six months, but that is in the noise; adjusting my watch for a different time zone typically has this effect.
Overall, the watch is a great timepiece, and seems to be holding up better over time than a similarly-priced Citizen model I purchased a few years ago (which I have admittedly abused...) I am rating it a four, only because the screw-down crown can be a bit difficult to operate, and the magnifier over the date window is not effective.
