Please be sure to read the description. This is a Homer Date from the 1960s-70s. The case and crown have been replaced. The mainspring should be wound gently as it is handmade. The crown is shorter, so it takes some skill to pull it out. You can pull it out with a click by inserting your nail into the gap, so be careful not to pull it too hard. The back cover's waterproof packing has been replaced, and magnetism has been removed using a demagnetizer. The dial and back have been lightly cleaned. The back cover is skeleton, and the windshield is mineral glass. (The case is an imported product) There are no operational problems, and the daily rate is about 1 minute. (The timegrapher shows a daily rate of about 15 seconds, but I'm estimating a bit more just in case) Since it's a 60-year-old item, I cannot guarantee water resistance, so please be careful. As you can see in the photos, there is some damage on the left side of the dial. It's not rust, but it appears to have occurred during the case replacement. Also, there are some scratches on the windshield. They are not noticeable unless you look closely, but please be aware. The inside of the movement looks clean with no rust. Considering its age, the condition is good. I purchased it 3 years ago, and it had been overhauled at that time. I will not disclose the name, but I purchased it from a watchmaker who also has a YouTube channel. I trust him because he also works on watches with complex mechanisms. Due to various circumstances, I am unfortunately selling it, but I hope someone who will cherish it will purchase it. I will attach the timegrapher data, but it is only a simple measurement, so please use it as a reference. The original case is still available, so I will send it together. Please note that the original belt and crown are not included. I will also include some mainsprings, but they will need to be modified, so please consider them as extras. I will also include a leather belt as an extra. I will upload photos of it later. Please comment if you have any questions. ~Details~ No hacking seconds. No quick date setting. (You can sometimes advance the date by moving the hands back and forth around the date changeover, but this is not recommended as it puts a strain on the parts. Please adjust it by turning the hands forward slowly). #Homer #HomerDate #Antique #Mechanical #SeeThroughBack #SkeletonBack
