In the case of Rolex watches, two that will be mentioned frequently are the Submariner and the GMT-Master II. Both are good for use but with some distinguishing features. Now let us consider why each of these is unique and figure out how to help you choose the one that is perfect for you.
The Basics: What Are These Watches?
The submariner came to divers in 1953. The GMT-Master was succeeded by the GMT-Master II in 1983 and was made for many travelers. It has evolved but they are what they were created to be
Here’s a quick look:
Feature | Submariner | GMT-Master II |
---|---|---|
Made for | Diving | Traveling |
Water resistance | 300m | 100m |
Bezel | One-way turning | Two-way turning |
Special feature | Dive time tracking | Multiple time zones |
How They Look: More Than Meets the Eye

You might think these watches look alike, but they’re not. Let’s check out the differences:
Submariner:
- Big, easy-to-see markers
- Date at 3 o’clock (on some models)
- Bezel with numbers every 10 minutes
GMT-Master II:
- Extra hand for second-time zone
- Date at 3 o’clock
- Bezel with 24-hour markings
The Submariner looks simpler. The GMT-Master II has more going on with its dial and bezel.
What’s Inside: The Engines of These Watches
Both watches have great movements, but they’re not the same.
Submariner uses Caliber 3230 or 3235:
- Keeps time for 70 hours when not worn
- Very accurate
- Doesn’t mind magnets
GMT-Master II uses Caliber 3285:
- Also lasts 70 hours
- Can change hour hand separately
- Good with magnets too
The GMT-Master II’s movement lets you change the main hour hand without messing up the minutes. It’s handy when you’re changing time zones.
Bezel Talk: More Than Just Looks
The bezel (that rings around the watch face) is where these two really show their differences.
Submariner bezel:
- Turns one way only
- Helps track dive time
- Usually black, but some are green or blue
GMT-Master II bezel:
- Turns both ways
- Helps track another time zone
- Often two colors (like red and blue)
The Submariner’s bezel is all about safety underwater. The GMT-Master II’s is about keeping track of time around the world.
Bracelets: What’s Holding Your Watch?
Both watches come with Rolex’s tough bracelets, but there are some differences:
Submariner:
- Oyster bracelet only
- Has a Glidelock clasp for easy adjusting
GMT-Master II:
- Oyster or Jubilee bracelet
- Easylink for small adjustments
The Submariner’s bracelet is made to fit over a diving suit. The GMT-Master II gives you a choice of styles.
Special Features You Might Not Know About

Here are some cool things about these watches that not everyone knows:
Submariner:
- Helium escape valve (on Sea-Dweller model)
- Cerachrom bezel that doesn’t fade
- Chromalight lume that glows blue
GMT-Master II:
- Can track three time zones with the bezel
- Some rare models have meteorite dials
- Bezel colors have nicknames (like “Pepsi” and “Batman”)
These features make each watch special in its own way.
How They Wear: Comfort and Style
Wearing a watch is personal. Here’s how these feel:
Submariner:
- A bit thinner and lighter
- Fits under sleeves easily
- Looks good with anything
GMT-Master II:
- Slightly thicker
- Colorful bezels stand out more
- Great for business and travel
The Submariner might be better if you want something that doesn’t stand out too much. The GMT-Master II is for you if you like a watch that gets noticed.
Prices and Getting One: It’s Not Easy
Both watches cost a lot and can be hard to find:
Model | Starting Price | Availability |
---|---|---|
Submariner | About $8,000 | Hard to get |
GMT-Master II | About $9,500 | Even harder to get |
You might have to wait or pay more than the list price to get one. Some people even buy other Rolex watches first to have a better chance at getting these.
Picking the Right One: Questions to Ask Yourself
Choosing between these isn’t easy. Think about:
- Do you dive or travel more?
- Do you like simple or complex watches?
- What colors do you prefer?
- How much are you willing to spend?
Your answers can help you decide which one fits you better.
The Little Things: Details That Matter
Let’s look at some small but important differences:
- The Submariner’s hands are a bit wider for better underwater visibility
- The GMT-Master II’s date changes instantly at midnight
- The submariner has a bigger crown for easy use with gloves
- GMT-Master II’s extra hand makes one full turn in 24 hours
These little things can make a big difference in how you use and enjoy the watch.
Care and Keeping: Making Your Watch Last
Both watches are tough, but they need some care:
- Get them serviced every 10 years
- Rinse the Submariner with fresh water after swimming in the sea
- Be careful not to scratch the bezel (especially on the GMT-Master II)
- Keep the crown screwed down when not setting the time
Taking good care of your watch means it’ll last for years and maybe even generations.
Wrapping Up: Two Great Choices
These two are simply amazing watches; the Submariner and the GMT-Master II. The Submariner is great if you like history and the sea or like to be fashionable and traditional. Therefore, the GMT-Master II is ideal for people who travel a lot or who prefer a model with extra functions.
No matter which of them you choose, you get an effective, precise, and recognized watch. Just be prepared to explain to friends that there is a Rolex on your wrist!
As always, a watch which you are happy to see every time you put your hand on it is the best. Therefore, which one do you think will you choose?
