Tudor Pelagos Titanium Grade?

[Pinchy]

Look, ultimately this is really pointless discussion, but one that I often have to answer when people delve into wether the pelagos is good.

What source can substantiate claims of which grade titanium is used?

Many claim its pure titanium (grade 2).

Most articles seem to claim a titanium alloy of titanium aluminum, vanadium (grade 5).

Is there any actual source either official or via conducted tests?

You had me at the start.

Most watch buyers wouldn't know grade 2 from grade 5 if it bit them on their HEV. The Pelagos is good.

I have to say I'm a little confused.

Are you saying you need to know what grade of titanium used in the Pelagos before you can decide if it's "good?"

I'm with Dan. Of course it's good. And I don't know sh$t about titanium grades.

But I do know watches.

Out of curiosity as an owner, what is the difference between the two types?

The Pelagos is a great watch and I could have the discussion that once the categories for analysis and comparison are made it is the best or one of the best dive watches for the money on the market. Not sure how the grade of Titanium figures into a discussion on the watch or impact on performance based on the grade of titanium.

I was always interested in the answer to this, I had assumed it was grade two and have never seen anything to say it might be grade 5.
As to why it matters grade 2 is a lot softer than grade 5.
I bought a grade 2 titanium watch just to see if the scratches were self healing as I’ve read and they are not, I’ve just read that it’s grade 5 that lets the scratches oxidise so hides the scratch and if that’s true which I now doubt, that would be a very good reason to have grade 5.

For most, it won't make a difference. The Pelagos is a great watch. The grade tends to come in discussion with how easily the metal marks or 'scratches'. Grade 2, as Pinchy noted, is pure alloy and is a softer metal. Grade 5 (where you have an alloy with those additional metals/materials) tends to make it a stronger metal.

I have not seen anything definitive from Tudor on which grade they use. Most members Pelagos' look great in pictures even if they are daily wearers (there are ways to "polish" the titanium with erasers, etc.). I have seen Omega note their grades - for example their Seamaster Pro 300 Ceramic Titanium uses Grade 5.

It’s Grade 2

For watches, the most common forms are Grade 2 and Grade 5 titanium. Grade 2 is “commercially pure” titanium and provides light weight and corrosion resistance but isn’t quite as strong as alloys like Grade 5. Grade 5, or Ti 6Al-4V, is titanium alloyed with 6% aluminum and 4% vanadium. The resultant alloy increases strength, as well as heat and corrosion resistance. In pricier watches, expect Grade 5.

Yep, grade 2 per the
Tudor sales rep who told me when I asked

Whatever it is, it would be 10x better in Stainless Steel

The Pelagos would be a Sub-killer if they did that, so they'll leave it as the ugly duckling

Disappointing, considering that Omega and other good brands use grade 5.

[Gab27]

That is a little strange. I am not sure why they would not use 6Al-4V all over unless they liked the cosmetic finishing of Grade 2 more? Functionally, 6Al-4V seems potentially preferable?

6Al-4V is more expensive, but, to my understanding, not drastically and not to a degree where I would think that this would play a major role in their decision given the amount of titanium is relatively limited for a product with a high price tag?

I suspect that Rolex will be rolling out full Grade 5 titanium watches in the near future, and you know how big brother always has to have one on little.

Practically speaking, Grade 5 allows the watch to be polished and have higher levels of finishing which this watch would not utilize. The newest Bond watch is also Grade 2, despite its 2-3 x price tag.

Not sure, but I’ve owned a two liner since the initial release and beat the tar out of it. Still looks great with no damage to the case or bracelet. It takes a beating much better than my heritage chrono, which shows a lot more dings and is mainly worn at work.

did a bit of research at the time i had a custom titanium bicycle built.

The different alloys each had their strengths and weaknesses and came down to a compromise between strength and resilience, stiffness and flexibility desired for the application.

In the end I would find it hard to believe the limitations of one alloy over the other would be approached in a watch case, essentially a brick of titanium.

The only priority I can think of that would be a concern is corrosion resistance. This would come down to the manufacturing process and environment, not the grade of titanium. Provided it was manufactured correctly there should be zero concern of corrosion resistance.

FYI some good reading on the alloys from the different ti bike manufacturers.

Maybe the buckle on the rubber strap but the Pelagos case back & clasp are stainless steel.

Considering this official reply is wrong about the clasp... who knows if they are correct about anything else...


Grade 2 has better corrosion resistance than 5. It's really pointless ultimately, but some people do snub their nose at grade 2 despite it being arguably a better choice for a dive watch.

I understood the strap buckle vs the bracelet clasp?

As far as the case back doesn’t the deepsea have a titanium case back? Is it something to do with using disimimilar metals?

My thoughts as well.

However, I'm still sticking with my story. Whatever they use to make the watch, I'm firmly convinced it's going to outlive me.

I don't see the official reply as wrong. I understand the reply is regarding the Pelagos FXD and the buckle material. The Tudor website clear states the regular Pelagos bracelet clasp is stainless.
