This is a masterpiece, the Omega "3210.51". It's a pre-owned item that has been overhauled and is sold for approximately 350,000 yen or more in the used market. I purchased this watch about 6 years ago in excellent used condition. I bought it to match with suits, but it was too expensive for the seller, who is rather frugal. Since my workplace allowed casual attire, I've only worn it two or three times before listing it for sale... For the past 5 years, it has been completely on display. Also, I had it overhauled by Watch Hospital about 4 years ago. It cost around 40,000 yen. It was originally in good working order, but I sent it in just to be safe. I can't find the itemized bill or the replaced mainspring, either electronically or physically, so I will add images as soon as I find them. I've been using other watches until today and haven't had a chance to wear this one, so I felt it was a waste and decided to list it for sale. I am listing this at a lower price than the market price because it does not include the "box, guarantee, and extra metal bracelet links." The original metal bracelet was polished during the overhaul, and I haven't worn it since, so it's in good condition. However, please understand that this is a pre-owned item that has been overhauled and stored. The seller's wrist circumference is about 17.5cm, and there was about one finger's worth of space. I think it's possible to adjust it with the buckle. Also, as a bonus, I will include a handmade genuine crocodile leather belt and a D-buckle that fit this watch with a lug width of 19mm. These cost over 15,000 yen together, and I think they will give the watch a luxurious feel that matches the main body. I bought these in case I got tired of the metal bracelet, but I only tried them on once and haven't used them since. I have applied a special cream to the leather, so please rest assured. I guarantee that this is a genuine, authentic product, as it has been overhauled in the past. However, due to the prevalence of counterfeit products, please refrain from returns to prevent swapping. Due to the high price of this item, please only purchase if you can agree to the above conditions. Also, as stated in my profile, I will not be offering discounts. I will lower the price or relist the item at my own discretion, so please refrain from comments. Thank you. ★
