Review: Surprisingly affordable sapphire face watch - This is the 1st watch I've ever had with a sapphire face and am very pleased. I was familiar with how durable and scratch resistant sapphire is because of my work with camera lenses in sewer inspection cameras. (which for obvious reasons need to be as durable as possible) I was always aware high-end watches like Rolexes used sapphire but I'm too cheap to buy one of those and I'm much to rough on my watches to feel right about wearing something that expensive on my arm even if it was given to me. After 8 months of use it still doesn't have any scratches on it. Admittedly, if I'm doing something like cutting down trees, working on a vehicle, etc., etc., I wear an old watch but even so my modus operandi involves accidentally hitting my watch on walls, shelves, door facings, and so forth. I'm left-handed and wear my watch on my left arm because I got tired of explaining to people years ago why my watch was on the wrong hand so I just switched it. As a result of wearing watches on my dominant hand they get abused. The titanium case is nice too. I like the looks of the case and the watch is definitely the lightest metal band watch I've ever worn. I bought the watch shortly before Christmas when it was on a good sale but even at the list price it's reasonable for a quality watch.
Review: Great large face for my aging eyes - Great looking watch. Keeps good time so far. This is my 3rd titanium citizen watch. My first, 27 year old one, finally broke and it would cost just as much to fix it as it is to buy a new one(when on sale) so this is the replacement for that one. Here’s hoping it lasts as long as the last one. Like the larger face since my eyes are not what they used to be, unfortunately the date window is still little small.
