Never need to open a case. Please review images to make your judgment on cosmetic condition. You will get what you see. As an used vintage item in general, there might be some dirt, scratches, and/or other forms of wear. This watch is currently running smooth, keeping accurate time.
But we still can NOT guarantee battery life due to various reasons such as unknown shelf time. Due to the nature of used/vintage watch, we can't guarantee long term functionality and accuracy. Typically, for quartz watch, if it runs, it will run pretty accurately. For approximate size of the watch and length of band, please see images. Please be advised that this is an used watch; its band may have been adjusted (shortened, links removed) to fit wrist of the previous owner; we DON'T have extra links.
So it is very important to make sure the overall length will be long enough for your wrist. Gender classification is strictly our own opinion.Therefore, it is very important to make you own assessment on the gender based on style and size shown in the images. Some watches, especially those with leather bands, may have certain smells inherited from their previous owners such perfumes, body mists, or even storage. Although these smells will fade out soon or late, they might not be suitable for particularly smell-sensitive buyers.
We do try to avoid listing the items with strong smells. However, due the nature of used items, we can't 100% guarantee all watches are smell-less. We can NOT guarantee water resistance or water proof. Unless and only if you can test waterproof capabilities professionally, we don't recommend to use any used watches in submerged environments such as swimming or shower due to the fact that the gasket rubber and/or other waterproof parts could age and harden when being old.
