This Citizen hand-wound watch has 17 jewels and currently has a power reserve of approximately 40 hours. The accuracy may vary slightly depending on temperature, position, etc., but as an example, it gained +10 seconds over 24 hours from December 27th to 28th. The case back is a screw-back type. According to information I found online, it appears to be a Homer model for export, with differences in the dial's Citizen logo and other markings. "Para Water" is changed to "Waterproof" and "Para Shock" to "Shock Proof." The movement is stamped with the Homer mark. The case is a slightly small 32mm, so it may not suit those with larger builds. The strap is likely lizard skin, but I'm not certain. The lug spring bars are original, so if you're concerned, I'll include new spring bars for you to replace them. It will be shipped via Yu-Packet Plus.
