Now, let’s move on to the comparison between the Grand Seiko SBGE245 and the Rolex Oyster Perpetual Explorer II. The Grand Seiko is a limited edition Spring Drive GMT watch with a rotating bezel and a stunning red/burgundy metallic dial. It is larger and thicker than the Rolex Explorer II, and its bracelet features more design details and has strap tool apertures. On the other hand, the Rolex bracelet is more plain and has a lift lock clasp. The Grand Seiko case is more complex with differential finishes and a black polish known as Zaratsu plate finish. The bezel of the Grand Seiko is crisp and distinct, with a metallic plate and fully loomed bezel underneath a sapphire cap. The Grand Seiko dial has superior detailing and finishing with gold accents, faceted indices, and a power reserve scale. Powered by a spring drive movement, the Grand Seiko combines quartz precision with a mechanical soul. In comparison, the Rolex Explorer II has a simpler, matte black dial with large white gold indices and a radial finish. The Rolex is thinner and easier to wear with a cuff, and has a longer warranty and more clasp flexibility. It also carries more brand cachet and has a timeless design. However, the Grand Seiko offers a rotating bezel with additional functionality, better loom on the dial and bezel, along with a longer power reserve. It is also more affordable and rarer, with only 600 pieces produced compared to the more widely available Rolex Explorer II. Ultimately, the author’s personal preference leans towards the Rolex, but individual taste and preference may vary.

Grand Seiko Spring Drive GMT SBGE245 Specifications

The Grand Seiko Spring Drive GMT SBGE245 is a timepiece that combines Japanese precision with timeless elegance. It features a slightly smaller 40mm case diameter, making it more suitable for those with smaller wrists or those who prefer a more understated look. The case is crafted from stainless steel and features a combination of brushed and polished finishes, adding to its overall appeal.

One of the standout features of the SBGE245 is its dark blue dial, which offers a visually striking contrast to the silver tone of the case and bracelet. The dial is adorned with luminous markers and hands, ensuring easy readability in any lighting conditions. Similar to the Rolex Explorer II, the Grand Seiko Spring Drive GMT SBGE245 also features a date display, located at the 3 o’clock position.

Inside the SBGE245 beats Grand Seiko’s renowned Spring Drive movement, a groundbreaking technology that combines the accuracy of quartz with the beauty of mechanical watches. This movement offers a smooth sweeping seconds hand, a signature characteristic of Spring Drive watches. With a power reserve of approximately 72 hours, the SBGE245 provides ample energy to keep the watch ticking even during days of inactivity. Like the Explorer II, the SBGE245 is water-resistant up to 100 meters, making it suitable for various water-related activities.

Dual Time Zones and Date Display

Both the Rolex Explorer II and the Grand Seiko Spring Drive GMT SBGE245 offer dual time zone functionality, allowing the wearer to keep track of two time zones simultaneously. This feature is particularly useful for frequent travelers or individuals constantly communicating with people in different time zones.

In terms of date display, both watches feature a date window located at the 3 o’clock position. This functionality is beneficial for those who rely on their timepiece not just for telling time but also for keeping track of the date. It ensures convenience and practicality for everyday wear.

Power Reserve

The power reserve of a watch indicates how long it can continue to operate without being wound or worn. The Rolex Explorer II is powered by the Caliber 3187, which offers a power reserve of approximately 48 hours. This means that if the watch is not worn for two days, it will still keep time accurately. This feature is particularly useful for those who rotate their watches in their collection or for individuals who don’t wear their watch every day.

On the other hand, the Grand Seiko Spring Drive GMT SBGE245 boasts an impressive power reserve of approximately 72 hours. This extended power reserve ensures that the watch will keep running even if left unworn for several days. This can be advantageous for those who may not wear their watch regularly or for those who travel frequently and may not have access to a watch winder.

Water Resistance

Both the Rolex Explorer II and the Grand Seiko Spring Drive GMT SBGE245 offer a water resistance rating of up to 100 meters. While neither of these watches is specifically designed for diving, they are both suitable for everyday wear and can withstand water splashes, rain, and even brief periods of swimming without compromising their performance or durability.

The 100-meter water resistance rating provides reassurance that the watches can handle humidity, accidental water exposure, and general moisture associated with daily activities. It’s important to note, however, that neither watch should be submerged in water beyond their respective water resistance limits, as doing so may lead to damage or malfunction.

Dial Styles

The Rolex Explorer II comes with a white dial combined with black hour markers and hands, providing a classic and iconic aesthetic. The contrasting black and white elements enhance legibility and make the watch stand out on the wrist. The luminescent hour markers and hands ensure that time can be read easily even in low-light conditions.

On the other hand, the Grand Seiko Spring Drive GMT SBGE245 features a striking dark blue dial. The color is rich and deep, creating a captivating visual contrast against the polished silver case and bracelet. The addition of luminescent markers and hands ensures optimal visibility, regardless of the lighting conditions.

Unique Features and Design Elements

Both the Rolex Explorer II and the Grand Seiko Spring Drive GMT SBGE245 are known for their unique design elements, which contribute to their individual charm and character.

The Rolex Explorer II is famous for its distinct orange 24-hour hand, which is designed to facilitate the tracking of a second time zone. This feature allows the wearer to differentiate between day and night hours in a different time zone, aiding in the adjustment of schedules and minimizing confusion caused by time differences.

The Grand Seiko Spring Drive GMT SBGE245, on the other hand, showcases Grand Seiko’s signature lion emblem on the case back. This emblem represents the brand’s commitment to precision, quality, and innovation. It’s a subtle yet distinctive detail that sets the watch apart.


In conclusion, both the Rolex Explorer II and the Grand Seiko Spring Drive GMT SBGE245 are exceptional timepieces that offer a combination of style, functionality, and precision. Ultimately, the choice between these two watches will depend on personal preferences, brand affinity, and desired features.

The Rolex Explorer II is an iconic and highly recognized luxury watch, known for its robust construction, classic design, and the brand’s prestigious reputation.
