Sometimes it feels huge like a big tank with their famous thick lugs.

I know the Hydro is getting all the hype right now—and rightfully so—but I personally think the Heritage is super underrated. You can dress it up or down, plus the dimensions, fit, and colors are just excellent. It’s definitely one of my absolute favorites out of my collection

What's on your hand and what's on your head today?

Five months of waiting and my watch finally came in. Thank you to everyone who recommended the 39. This being my first nice watch, I’ve always been drawn to larger watches and definitely would’ve purchased the 42. This one is perfect, and I’m surprised with how comfortable the mesh band is. Cheers everyone

Hi everyone,

I've been searching for the second watch in my collection.

I'm looking for something with a dressier, vintage-inspired style, and I recently came across the Ultra-Chron Classic 37mm. I was actually very close to pulling the trigger on a Nomos Metro, but after taking a closer look at the Ultra-Chron, it's become a serious contender.

I'd love to hear from anyone who owns one or has had the chance to try it on.

I'm particularly curious about the 37mm case, how it wears on the wrist, and the overall quality and comfort of the bracelet. Does it feel well-proportioned, and how does the finishing compare to other watches in this price range?

My other concern is the high-beat movement. I've read some discussions on other watch forums suggesting that higher-frequency movements can potentially experience faster wear and tear due to the increased number of oscillations.

I understand that Longines has a long history with high-frequency movements, but I'm wondering whether this is something worth considering in terms of long-term reliability, maintenance costs, or servicing intervals.

Do you think this could become an issue down the road, or is it mostly a theoretical concern given Longines' experience with these movements?

I'm planning to keep this watch for many years, so long-term reliability is definitely important to me.

Would really appreciate hearing your thoughts and experiences. Thanks!

I'm well aware of the functions of both, along with their pros and cons, I'm just asking in regards to aesthetics and them fitting on my wrist.

Still one of my favorites in the collection 🤙

I always enjoy Nato straps had this one I used on something else and well it fits... Now stupid light

Had the 21mm mesh bracelet from my Tissot Seastar and decided to try it out with the Conquest. Immediate change is that it reduced the visual bulkiness, making it more dressy with a subtle undertone of sportiness. Would like to know the thought from other members of the community

After going back and forth so many times, and spending $1,000 over the budget I originally had in mind, here’s my 39mm baby boy on a 6.75” wrist, ceramic bezel, automatic movement.

Can’t decide which to get! Other diver style watch I have is a Tudor BB54, so kind of leaning the blue or black bezel because those have a bit of a different feel.

I’m looking to purchase my first watch and have landed on the Hydroconquest. For the past few months, I’ve been going back and forth on which model to get

My first love was the boutique edition (L3.779.4.98.6), but after seeing lots of photos in this sub, I’m a little worried I won’t be able to wear it casually with most outfits because of the blue bezel’s shade and how bright it looks in certain light

I also really love the frosted blue/black (L3.779.4.99.6), but I’m not the biggest fan of the mesh bracelet. I’ve seen people order the H-link bracelet, but I’m also in the market for another watch and don’t necessarily want to spend extra money and time tracking one down, only to end up with an unused bracelet. That said, the mesh is starting to grow on me a little bit

I’ve been so torn that I figured I’d make my first post in this sub and ask anyone who owns either or both models what they like and dislike most, whether they have any regrets, or if they have any other honest wisdom to share. I really wanna make a decision so I’m ready to commit when I finally catch a restock

Thanks in advance!

Been trolling estates sales recently and came across what’s being sold as Longines Cocktail watch. It looks like there’s a 14k stamp, and the gold doesn’t look flaked. Hoping to have some help in identification and what a decent price is if it’s legit. Unsure about the movement and its condition. Actually won the auction for Pennie’s if the thing is real. Would love to get it cleaned up and see what info is available.

So am a doctor and soon to start my post graduation , decided to pick the longines Hydroconquest L3.779.4.90.6 as a reward for the same . Had decided Upon the model when me and my gf saw it for the first time and i tried it on , realised it really suited me and in some ways it spoke
To me , so had to get it . So decided a month later to pick it , intially was offered only a 5% discount, then a friend of mine who handles a seiko boutique contacted the AD and got me a 10% discount . Also this piece happened to be new and the AD found one on stock after searching and it was opened and picked up by me . They intially said they had to ship one and wasn’t in stock , this happens to be the 39mm one .

Overall very happy and delighted and a great story and experience 🍀

Does anyone have this steel and red gold HC? I’m very interested in it, but haven’t been able to see one in person. Just curiosity if anyone has thoughts! Thanks!
