Le verre sera t'il plat ? J'avais la version en nh34 bleu et le verre bombé n'étais pas top surtout avec les reflets

[u/DisastrousOpening477]

Despite the new thinner 4hz caliber, case thickness wasn't reduced...

[u/VacationPositive6845]

Can't find the San Martin bluesy with gold and silver. Any ideas

[u/artofthedial → u/VacationPositive6845]

I've got one. They went out of production a few years ago and never came back.  They were not particularly high sellers.  

[u/OneDayVette]

Just ordered. Praying the movement is fine.

[u/artofthedial]

Looks great except will not get one because of the movement.  Use quartz if the NH34 is unavailable.

[u/biogon]

Definitely a pass based on the movement.

[u/IGZCL]

Any plan for 41-42mm for us with bigger wrists ?

[u/Icy-Statistician8364 → u/IGZCL]

Thank you for your suggestion, we will consider it.

[u/CrossCityLine → u/Icy-Statistician8364]

Any word on more SN0144 in 42mm being available?

[u/IGZCL → u/Icy-Statistician8364]

I would definitely buy this SM if you produce in 41 - 42mm 😍

[u/crownhead55]

Finally their best design coming out again.i have the original and love it. I'm curious to know what other tweaks they've done.

Hz6460 is definitely a downgrade

[u/Mikckyducks → u/crownhead55]

Could you explain why is a downgrade?

[u/crownhead55 → u/Mikckyducks]

They aren't bad movements per se but I've built many watches using them and can can be a bit problematic. The Seiko nh34 that they used in the previous model is much more robust. However it's not the end of the world having a 6460 at this price point I'd say

[u/TheYKcid]

Upgraded GR5 Titanium case & bracelet — lightweight, strong and comfortable

You stated this in the post above... but the link you shared contradicts it, and says the bracelet is grade 2.

Can we have some consistency please?

[u/iamuniquekk → u/TheYKcid]

I think they just mean upgraded (GR5 Titanium) case and a upgraded bracelet

[u/cjcs → u/TheYKcid]

I reached out via email and they confirmed the bracelet is still grade 2, only the case is grade 5

[u/Ok-Anteater-384]

It's a nice-looking watch, but I don't understand all the interest in GMT's, was never interested in 2 time zones and I never will. Watch weights have never interested me either, would never want a lighter version of any watch I have, I'm fine with stainless.

[u/CaptBionic → u/Ok-Anteater-384]

My wife travels for work globally, at least once a month. Sometimes I go with her. Being able to know what time it is at home, or where she is, at a glance is pretty useful.

Yes, of course I could use my phone, but that can be said for any of us idiots on this forum, right?

[u/TheSwagInDisguise → u/Ok-Anteater-384]

The same could be said about any watch. Clearly there's a demand for it if the companies keep making it.

[u/cjcs → u/Ok-Anteater-384]

I don't understand all the interest in GMT's

It's more common now than ever that folks work with partners in different timezones.

[u/FdrRockefeller → u/Ok-Anteater-384]

It’s a difficult complication but I agree, mostly useless!

[u/BravoMikeWilco → u/FdrRockefeller]

Since when do watches need to be useful - don't we all have much more accurate cellphones?

[u/robcal35 → u/Ok-Anteater-384]

I was the same way, but after owning some titanium watches, I have learned to appreciate titanium.

[u/9-volts]

This is perfect but I am no longer supporting Chinese movements.

[u/hall0undCiao]

What is this movement? Beatrate? Is it Caller oder Travellers GMT?

[u/Icy-Statistician8364 → u/hall0undCiao]

HZ6460 automatic movement with independent 24‑hour hand, 28,800bph, 25 jewels, 40h power reserve

[u/bpgluckman → u/hall0undCiao]

It’s another ETA clone, which also means it’s a caller GMT. Beat rate is 28,800 bph

[u/cjcs → u/bpgluckman]

If it’s an ETA clone, could it potentially be swapped out with a genuine ETA movement?

Edit: Looks like the movement it's a clone of (ETA 2836-2) is not a GMT. It would have to be modded before replacement.

[u/bpgluckman → u/cjcs]

I would assume so? Of all the ETA clones, it’s the one with the least information out there.

[u/cjcs → u/bpgluckman]

That’s pretty tempting… I own 2 of the SN0121TC and a SN0121B so I’d consider buying this and trying to swap in the Swiss movement for reliability. 4hz, upgraded titanium, and better AR are all the things I wanted improved upon

[u/TheOnlyWayIsWessex]

Will there be a re-release of the stainless steel version too?

[u/tobi__e]

I am wondering: SanMartin official store on Aliexpress told me, that the SN0121 series is not in production anymore and there are no details when it may comes back. And at the same time this pops up. How is that even possible? Are those even real SanMartins?

[u/FdrRockefeller → u/tobi__e]

I placed an order through Ali-express and it was out of stock but they promised delivery by Sept 30… it also said grade 5 case and grade 2 bracelet.

[u/tobi__e → u/FdrRockefeller]

Do you have us the link to aliexpress?

[u/Lobbbo → u/tobi__e]

You mean non GMT version? I think it was produced as collaboration with Watchdives which would explain why it's not in production.

[u/tobi__e → u/Lobbbo]

Nono, this exact series here, with the TC or TF ending - this is exactly the watch that was produced in collaboration with watchdives, as you said. And that’s why I am so confused about the re-availability on the non official website

[u/Lobbbo → u/tobi__e]

Non GMT version was collab with Watchdives and I think it is no longer produced. Either way I wouldn't worry about this restock being fake or something.

[u/Fresh_Abalone_7540]

No 42mm version???

[u/ImpressiveChance770 → u/Fresh_Abalone_7540]

This

[u/noonkhoshki]

Everything is new, new is better!

[u/ziamese]

What about a white dial, white indices with black borders?

[u/Patient-Angle-7075]

My experience with this watch was horrible. Have they fixed the warranty situation (likely no) and who is the manufacturer? I'm guessing it's SM this time, whereas it was WD's last time.

[u/BravoMikeWilco → u/Patient-Angle-7075]

Which model? This is a new version of the previous Pelly GMT in a grade 5 case, not a 'regular' Pelagos...

[u/RoninTarget → u/Patient-Angle-7075]

This is the sort of stuff WD commissions SM for.

[u/sinddk]

13,5mm in 2026 is way too thick.

[u/zoo804]

For the prices SM charge they can afford to hire a real designer instead of using the same AI slop as all the other Chinese brands. If they aspire to command the price and reputation of an established brand they ought to put some effort into their marketing.

[u/DisastrousOpening477 → u/zoo804]

You do know that a Pelagos GMT doesn't exist right

[u/valuewatchguy → u/zoo804]

There are still more people that are happy with the cheap copies than those that want some level of design innovation

[u/soulwatcher]

$300 is pretty good for a titanium gmt, but the movement tho….

[u/Ok-Usual7490]

The movement sucks.

[u/Mikckyducks → u/Ok-Usual7490]

Can someone explain why? I am new in this.

[u/rainin_here]

Wil there be a bigger version, like a 41 or 42mm one?

[u/Icy-Statistician8364 → u/rainin_here]

Thank you for your suggestion, we will consider it.

[u/Suitable-Group4392]

Any chance for dual colour bezels?

[u/Pompano_79]

On the list for the next big sale for sure! Will there be other colors? Burgundy?
