The polished 316L stainless steel case and bracelet offer a luxurious finish, while the sapphire crystal provides scratch-resistant protection.

Did You Know?

Did you know the GMT (Greenwich Mean Time) function on your Seiko Mod GMT Master allows you to track two time zones at once? Originally designed for pilots and frequent travelers, the GMT function uses a 24-hour hand and a rotatable bezel to display a second time zone. Simply set the bezel to the difference in time zones, and you’ll always know what time it is back home or in your destination, all at a glance.

For example, if you’re in New York and want to track the time in London, simply rotate the bezel to account for the 5-hour time difference. This handy feature is perfect for those who need to keep track of multiple time zones, whether for work or personal reasons.

Fun Fact: The GMT Master was initially developed for Pan Am pilots in the 1950s to help them navigate the increasing complexity of international travel. Today, the GMT feature remains a favorite among world travelers and aviation professionals.

Frequently Asked Questions

What's a Mod?

In the context of watches, a “mod” (short for modification) refers to customizing a watch to alter its appearance or functionality. This can include changing the dial, hands, bezel, crystal, strap, or even the movement of the watch. Mods are popular among enthusiasts who want to create a unique or personalized timepiece. Seiko watches are particularly favored for modding due to their robust construction, affordable price point, and the wide availability of compatible aftermarket parts.

Yes, you can adjust the size of the watch band yourself. Most watch bands come with adjustable links or holes to accommodate different wrist sizes. At Time Madness, we offer the option to adjust the band size before shipment upon request, and we also provide the necessary tools with each watch for your convenience.

Here are the general steps for adjusting different types of bands:

Metal Bracelet Bands:

Tools Needed: Spring bar tool and a micro screwdriver (provided with your purchase).

 

Remove Screws:

•Identify the screws on the side of the bracelet links that need to be removed.

•Use the micro screwdriver to carefully unscrew and remove the screws.

•Take out the necessary number of links to adjust the band to your desired size.

 

Reattach the Band:

•Align the remaining links and reinsert the screws.

•Tighten the screws securely with the micro screwdriver to ensure the band is properly fastened.

 

Organization: Keep the removed screws and links in a safe place in case you need to readjust or reattach them in the future.

Professional Help: If you’re unsure or uncomfortable with the process, consider taking your watch to a professional jeweler or watchmaker.

Yes, all our watches are original. At Time Madness, we pride ourselves on offering high-quality, authentic watches. While we specialize in modding Seiko and other brands’ watches, some parts we use are custom-made. The movements in our watches are always original, and depending on the parts selected, they are either from Seiko or custom-made by reputable suppliers. Our custom components are crafted with precision to ensure that each timepiece meets our stringent quality standards, providing you with a unique and reliable watch that combines originality with personalized customization.

A 3 o’clock or 4 o’clock dial refers to the position of the crown (the small knob used to set the time) on the watch face.

3 o’clock Dial: The crown is positioned at the 3 o’clock mark on the watch face. This is the most common placement and is typically found on many traditional watch designs.

 

4 o’clock Dial: The crown is positioned at the 4 o’clock mark. This placement is often used for ergonomic reasons, as it can be more comfortable for the wearer, especially when the watch is worn on the left wrist.

Both 3 o’clock and 4 o’clock dials offer unique aesthetic and functional benefits, allowing you to choose the style that best suits your preferences and comfort.

Yes, spring bars are included with every watch strap purchase. Additionally, we provide a tool to help you easily remove the current strap and attach the new one. This ensures that you have everything you need to quickly and securely change your watch strap at home.
