Head to Head: Seiko Titanium Case Grade 5 vs. Grade 2
When you hear the word Titanium, you would surely think of something premium, maybe even exclusive. This metal, or metal alloy is a celebrated one in the manufacturing industry, being the material of choice for products or structures that require more durability than steel can provide.
Before the 1970’s, Titanium was almost exclusively used for building airplanes and rocketships (we’re talking NASA) due to its strength and high heat resistance. Today, you will see this metal used in many other items, including but not limited to bicycles, surgeon tools, jewelry, and more.
One other industry that Titanium is slowly gaining traction in is the world of horology.
The First Titanium Watch
In the late 60’s, NASA started their Apollo missions, where they sent manned and unmanned rockets to the moon and around the Earth’s orbit. Stainless steel did not cut it for the creation of these rocket ships, which required a more durable material, and one that can withstand the extreme heats emitted by the boosters. What did they use? You guessed it - Titanium.

This is when Japanese watch brand Citizen took notice of the unique properties of this wonder metal and decided to create the world’s first watch made of this material: the Citizen X-8 Titanium Chronometer. It is not clear why this aspect of the watch has not been heavily advertised during the model’s debut, with Citizen opting to more prominently highlight the movement powering the watch.

To be fair, the watch also featured the Citizen Calibre 0820, one of the world’s first battery-powered and highly-accurate movements. And yet, the Titanium make of the X-8 Chronometer is what makes it desirable to collectors today. With 99.6% purity, this piece is very hard to find in present times.
They say only 2,000 pieces were ever made, making this a very rare collectible.
Watch Brands Using Titanium Today
Needless to say, the use of Titanium has since progressed and is being utilised by more and more watch brands today. Here are some of the more notable ones:

Being the pioneer in this category, it just makes sense that Citizen is a watch brand that would excel in making Titanium watches today. The Promaster Diver is a well-rounded timepiece with a friendly price tag. It is rated up to 200m and features solar charging, making it a very practical choice.

Since Titanium was a primary material for constructing aircraft, having a matching watch is not out of the picture. The IWC Pilot’s Mark XVIII is a vintage-inspired piece with a simple and legible face with beige lume. While the case may not be rated for deep diving, you can be sure that it is durable, thanks to its Titanium make.

Not to be outdone and left behind, Seiko has produced many Titanium watches over the years, and one of the best looking ones is no doubt the SBGA413. The Sakura-blossom inspired dial is encased in a “High-Intensity Titanium case,” which is perfect if you have an exclusive cocktail party at 7 and an MMA fight at 8.
namokiMODS’s Titanium SKX Cases
If you’re one of the lucky few who were able to snag one of our limited edition Titanium SKX cases last year, you’ve had an idea of how good of a material it is, especially for divers watches. It just makes sense! And we’re proud to be the first ones to use it as a material for a Seiko modding case.
Our NMK910 Titanium Case from last year.
Some of the reasons why this metal is a great fit for divers watches:
- Resistant to rust and corrosion. These two are some of the main problems with any metallic item that is regularly submerged in water, even stainless steel.
- Scratch-resistant. No matter how careful we are, we will always be scratching our watches somewhere. It could be a door, a kitchen countertop, the car keys, or scuba-diving equipment. It helps with peace of mind knowing that your watch is protected from all these.
- Lightweight. One of the most appealing properties of Titanium is its lightness compared to stainless steel, with people even reporting that a Titanium watch almost feels weightless compared to its steel counterparts.
- Hypoallergenic. No matter what skin type you have, you will never get a rash or any allergies with a Titanium case, unlike stainless steel which contains nickel, a metal that many people are allergic to.
- Anti-magnetic. We all know how magnetism affects a watch movement and causes inaccuracy with time-keeping. Having magnetic resistance is a must-have.
- That premium look and finish that you just can’t get with regular 316L!
In our first edition, we opted to go with Grade 2 or pure Titanium. This version is ‘more pure’ Titanium which actually makes it easier to mold and therefore more accessible price-wise.
After gathering community feedback, we are launching more Titanium SKX cases very soon, and this time, we’re leveling up by using Grade 5 Titanium!
Grade 2 vs.Grade 5
There are few but very important differences between these 2 grades of Titanium. The first and most important one is their strength.
Grade 2 is a commercially pure Titanium, while Grade 5 is mixed with Aluminum and Vanadium. The latter can be more than 3 times stronger than the former, and is the most widely used grade of this metal/alloy. It can also withstand higher temperatures than Grade 2. It is also because of this strength that
Grade 5 has “self-healing” properties. If you get scuffs or scratches on your watch, they will slowly disappear as the unoxidized portions of Titanium will create a grey patina upon contact with air. A neat trick that Grade 2 versions cannot claim! This means no additional coating is needed when treating this metal.
Time to get hyped, because namokiMODS is releasing not one, but two new Titanium Seiko cases very soon! We can’t share a lot of details at this time, but what we can confirm right now are the two styles of the upcoming cases. Both Grade 5. Both awesome.
Be sure to keep your eyes on your inboxes (subscribe to our newsletter now if you haven’t already) as we will be sending out a notification once these are released. It’s coming out soon!
Like our previous Ti case launch, we will be offering a 20% discount for the first 100 customers, while the next 100 will enjoy 15% off. The rest will be sold at 10% off until Cyber Monday on November 29.
We hope you’re excited modfam! Happy modding!
