This is a unique mechanical watch in what it offers, namely the alternation of the sun and the moon, hence the title "sun and moon," and objectively impressive, as its dial has many information and details, while it is also made of sapphire crystal. Additionally, the back of the case allows you to see the exceptional and accurate mechanism of the Orient. Its negatives are the relatively large thickness of the case, which makes it bulky, as well as the uncomfortable strap due to the clasp mechanism. However, I have not found a similar watch with these characteristics at this price (purchased for 237 euros) from a well-known company in the field.
