A watch is considered by many as an essential accessory because they make a fashion statement while telling the time. For this reason, all watch enthusiasts get only the best watches, preferably from a well-known brand such as Seiko. Seiko is a Japanese watch manufacturer that has been around for more than 140 years, a testament to its watchmaking excellence.

Seiko watches are notable for their precision, quality, and attention to detail. The company has always been at the forefront of watchmaking technology and innovation and has introduced numerous groundbreaking technologies. Even better, most Seiko watches can be modded in different builds to suit the wearer’s needs, such as the Nautilus. However, many people refuse to mod their watches because they think it is not worth it or do not know how. To help you with this, we will guide you in this article.

How Watch Modding Is Done

Watch modding involves changing the watch’s exterior, such as the strap, dial, bezel, or case. Of course, this can also be done to the watch’s interior components. To do this, you must first disassemble the watch, make the modifications, and reassemble it.

Watch modding is an excellent way to customize your watch and make it unique. It can also help you to make the most out of your watch and get the most out of it. It can also be a great way to add value to your watch, as some changes can increase the value of the watch.

Building the Nautilus

Watch modding is straightforward, but you will need certain tools and equipment. These include:

SKX007 Chapter Ring
SKX007 Crown
SKX007 Caseback
Seiko Dial
Flat Sapphire (includes a free case)
NH35 hands
NH36 Movement (or NH35, depending on your dial)
Nautilus Conversion Case
Nautilus Compatible Bracelet

Laying the Foundations

Once you have gathered your tools, you should choose a Nautilus-style case. Many options are available, so the choice is entirely up to you. As a recommendation, a two-tone black and silver Nautilus Case is a good generic build, though you can also choose another.

Choosing a Movement

A watch’s movement is the mechanism that powers the watch and keeps it ticking. It is worth noting that what movement you choose depends on your dial (more on that later). An NH36 movement is a good choice because it is the movement many Seiko watches use. However, there are times when you may want to choose differently.

If you want a watch with a date display but no day of the week, you should choose an NH35 movement. This movement will work well with a date-only dial, so the day wheel won’t get in the way. However, if you still want an NH36 movement, you can use it with a date-only dial, and it will still function properly.

On the other hand, an NH70 movement is recommended for skeleton builds. You will also need a gray movement spacer using an NH70 movement.

Installing the Dial

Once you have chosen the movement, you must install the dial. The dial is the part of the watch that you will see when you look at it, and it can be made from different materials such as metal, plastic, or wood. The dial should be installed carefully, ensuring the screws are tight and the movement is secured.

The hands are also vital because you must be able to see them clearly. Because of this, your watch hands must be the right size, shape, and color for your watch.

Installing the Sapphire

Installing a watch’s sapphire is tricky because it requires precise measurements. The sapphire should fit perfectly into the watch’s bezel, and any gaps can cause the watch to malfunction. Once done, you must secure it with a tiny screwdriver and some glue.

Case and Caseback

The case is the outer shell of the watch, while the caseback is the back of the case. The caseback is usually made of stainless steel or titanium and is secured with screws. When choosing materials for the case and caseback, you must ensure they are strong and durable enough to protect the watch from water, dust, and other elements.

Choosing a Bracelet

The bracelet is crucial because it will complete the watch’s look and must match the case and caseback. Ideally, the bracelet should be made of stainless steel or titanium, as these are strong and long-lasting materials. You should also consider the bracelet’s size and ensure it fits comfortably on your wrist.

Conclusion

Building a Seiko Nautilus will be challenging, but the effort will be worth it because you can get a unique, stylish timepiece. You have complete creative freedom when building the watch, so you can do as you please. All that matters is following instructions to the letter to ensure you get a quality product.
