Three Grand Seiko watches recommended for women. Is there a reason they fit so well? Choose the one for you based on your body type.

When choosing a watch, we often make a decision based on the inspiration we get from its appearance. However, have you ever felt that when you actually try it on, it just doesn't feel right? This is because the shape of a human arm varies depending on the bone structure. In this article, we will explain the characteristics of bone structures classified as "straight," "wave," and "natural." Furthermore, Grand Seiko, which now offers a wide range of sizes, will introduce watches recommended for each bone structure.

How do I find the right size watch for my wrist?

　I'm sure there are many women reading this article who have wondered what size is best when choosing a watch. This may be a prejudice, but in my experience, this may be a concern for women because they have fewer opportunities to try on watches.

　I've been in the watch industry since my twenties, and I've helped customers choose watches while also understanding the mysterious law of "what size just suits you for some reason." That's why I can say that what "fits you well" often has something to do with your body type. In other words, this law isn't a mystery.

　Here, we will explain the characteristics of each body type (straight, wavy, natural), and suggest recommended case sizes for women with each type of body type, using Grand Seiko's wide variety of models.

Want to choose a watch based on your body type? Start with a simple body type diagnosis!

　A bone structure diagnosis involves classifying your innate bone structure into three categories: "straight," "wavy," and "natural," and then determining the size of items that will suit your blue bone structure, as well as where to focus your styling to make you look more stylish.

　If you're having trouble figuring out which skeletal type you belong to, it might be easier to find out by showing your hands to friends and acquaintances. If you look at the hands of several people, you'll notice that there are differences in their skeletal structure. So, which type do you belong to?

Straight bone type

　People with a straight bone structure tend to have smaller hands compared to their height and firm palms. Other characteristics include a fleshy, three-dimensional hip line and small feet compared to their height.

Skeleton wave type

　If you have standard-sized hands and thin palms, you are likely to have a wave-shaped skeleton. This type of skeleton is characterized by thin, prominent collarbones and a low, flat hip line.

Natural bone structure type

　The hand size is large, and the bones and muscles are strong, giving the skeleton a natural look. The limbs are long, the shoulders are broad, and the bones and muscles are strong, giving the skeleton a natural look.

Grand Seiko, which now has a wide range of sizes, puts it into practice

　Now, let's take a look at which body type each of the three models with different case sizes will suit best. Note that this time, we're using a wrist size of 15-15.5cm as the standard.

Grand Seiko recommended for straight-framed watches: STGK031

　The recommended case size for a straight-framed watch is one that fits your wrist just right, neither too small nor too large. When wearing the watch on your wrist, it's best to choose a case that allows you to see the end pieces, the first link, and about half of the second link. If your wrist size is based on this standard, the STGK031, with a diameter of 30mm and a total length of 36.2mm, would be a good fit. When shortening the links, it's best to choose a size that allows one finger to fit inside, as is the mainstream.

Grand Seiko recommended for wave-shaped body types: STGF389

　The recommended case size for a wave-shaped body type is smaller than just right. When wearing the watch on your wrist, it's best to choose a case that allows you to clearly see the two links from the end piece. For a wrist size of around 15cm, the STGF389, with a diameter of 26mm and a total length of 32.9mm, would be a good choice. When shortening the links, adjust it so that it's larger than just enough for one finger, and wear it like a bracelet to match the delicateness of your wrist.

Grand Seiko recommended for natural body types: SBGW323

　The recommended case size for a natural body type is one that feels a little large for the wrist. When wearing the watch on the wrist, it is best to choose a case that allows the end pieces to be visible. This type has a solid frame, so even larger sizes can be worn comfortably. This type of body type is common among models. In this example, the assumed wrist size is 36.5mm in diameter and 42.7mm in length for the SBGW323, which has a case that feels thinner than the actual hand size. Therefore, when shortening the links, it is easier to achieve overall balance by choosing a size slightly larger than the size of one finger.

Let's find a watch that takes advantage of your bone structure!

　Your body type is one guide to finding out which size suits you best. If you feel like a watch "just fits" when trying it on, it may be because you chose a size that fits your body type well. Why not use your own body type as a reference to find a watch that will enhance the appeal of your wrist?
