The Standard Rolex Submariner Size

For many years, the standard case size of the Rolex Submariner remained consistent at 40mm. This size struck the perfect balance between rugged sportiness and refined elegance, making it wearable for a wide range of wrist sizes and occasions.

However, in 2020, Rolex made a significant update to the Submariner lineup by increasing the case size to 41mm. This may seem like a minor change on paper, but in the world of horology, even a 1mm difference can impact how the watch looks and feels.

Comparing 40mm vs. 41mm Submariner Models

Rolex Submariner 40mm (Pre-2020 Models)

Production Years: Up to 2020
Design: Slimmer lugs, smaller bracelet, more compact look
Wrist Fit: Best suited for wrists under 7 inches (17.8 cm)
Popularity: Widely appreciated by traditionalists who prefer the classic Submariner proportions

Rolex Submariner 41mm (Post-2020 Models)

Production Years: 2020 to present
Design: Slimmer lugs than the previous “Super Case” but a slightly broader appearance
Wrist Fit: Works well for wrists 7 inches and above, though still wearable for smaller wrists
Upgrades: Caliber 3230 or 3235 movement for better precision and power reserve

While the 1mm difference may not be visually overwhelming, it does affect the overall presence of the watch on the wrist. Many wearers have noted that the new 41mm version wears more comfortably due to slimmer lugs, despite the increase in diameter.

Why Size Matters When Choosing a Submariner

Choosing the right Rolex Submariner size is more than a matter of aesthetics—it’s about comfort, balance, and lifestyle.

1. Wrist Size and Comfort

The physical size of your wrist should influence your Submariner selection. A 40mm model may be better suited for slimmer wrists, offering a balanced and proportional look. In contrast, a 41mm model may appear more bold and modern, particularly on larger wrists.

2. Style Preference

Some prefer the vintage charm and understated presence of the older 40mm Submariners, while others lean toward the slightly more modern and robust look of the 41mm variant. Your personal taste in watch fashion plays a significant role here.

3. Daily Wear vs. Occasional Use

If you plan to wear your Submariner every day, comfort becomes even more important. The difference in size might affect how easily the watch slips under shirt cuffs or how noticeable it feels throughout the day.

Other Dimensions to Consider

The case diameter isn’t the only dimension that matters. Thickness, lug-to-lug distance, and bracelet width also contribute to the overall feel and appearance of the watch.

Thickness: The Submariner remains relatively slim for a dive watch, even in the newer 41mm models.
Lug-to-Lug: The change from 40mm to 41mm also slightly alters the lug-to-lug measurement, which affects how the watch hugs your wrist.
Bracelet Size: The updated 41mm Submariner comes with a wider bracelet and a more tapered clasp, enhancing stability and comfort.

Choosing the Right Model for You

Here are a few tips to help you pick the perfect Rolex Submariner size:

Try it on: Visit an authorized dealer if possible. Trying both 40mm and 41mm versions can help you understand how each size feels on your wrist.
Consider your wardrobe: If you often wear suits or fitted clothing, a smaller Submariner may blend better. If your style is casual or sporty, the 41mm model might make a stronger impression.
Think long term: Trends come and go, but comfort and versatility should guide your decision. Choose the size that you’ll be happy with for years.

Caring for Your Rolex Submariner

Whether you choose the 40mm or 41mm model, your Rolex Submariner deserves proper care and maintenance. One of the best ways to protect your investment—especially if you own multiple automatic watches—is by using the best watch winder.

A high-quality watch winder ensures your Rolex Submariner stays wound and keeps accurate time, even when not worn for days or weeks. This is especially useful if your watch includes date complications or other features that require resetting after being idle. Moreover, a premium watch winder stores your timepiece safely, reducing wear and tear and maintaining the watch’s internal mechanisms in optimal condition.
