The Fathom Handset. Vintage-Diver Character. Designed for the Great Fathom Dial.

A polished-silver handset with vintage-diver character — clean shapes and honest proportions that read instantly, the way a dive watch should.

These were designed alongside The Great Fathom Dial — the original pairing — and carry 100% Swiss Super-LumiNova® BGW9, Grade A being the highest-grade BGW9 on the market, for a long-lasting blue glow.

Lume pairs perfectly with our BGW9 parts.
On the Great Fathom dial — or any BGW9-lumed face — hands and markers glow as one design.

Designed for the Great Fathom.
Drawn up alongside The Great Fathom Dial, so proportions, lume tone and character land as one design rather than an assembly.

Swiss BGW9 glow.
100% Swiss Super-LumiNova® BGW9 keeps the vintage-diver face legible deep into the night.

Heads up — hands are one part of the build

Dial. Hands are paired with a dial. These were designed alongside The Great Fathom Dial — the original pairing — or browse the full dial collection in the Recommended tab.

Movement. Hands press onto the movement's pinions — check the fit list in the Specs tab against your caliber before ordering.

Will these hands fit my movement?

Check the Fit Movements list in the Specs tab against your caliber. The handset fits a wide range of Seiko movements — including 7S, 4R, 6R, NE and NH families — because they share a common pinion pattern. If your caliber is on the list, these hands fit.

What are the pinion sizes?

Hour 1.50mm, minute 0.88mm, second 0.198mm. The pinion is the hole at the base of each hand that presses onto the movement — these dimensions match the standard Seiko pinion pattern shared across the calibers in the fit list.

Can I use these on a GMT (NH34) build?

The hour, minute and second hands fit the NH34. A GMT build also needs a separate GMT hand, which is not included in this set.

Do the hands come with lume?

Yes — these hands are filled with 100% Swiss Super-LumiNova® BGW9 Grade A, for a long-lasting blue glow at night, with a clean metal finish for daytime wear.

Customers praised these watch hands for "fantastic quality" and "excellent lume." Reviews highlight superior finish, bright luminescence, and perfect fit. One customer noted "these hands rock hardcore!" Fast shipping and great packaging were frequently mentioned. Minor concerns: one compatibility issue with NH35A movement, and hands require gentle handling during installation.

These Hands Rock Hardcore! I especially love The Brightness of the Lume
Great lume and superior finish. Provides a great finishing touch
The hands are so well crafted. Quality is top notch. Lume is awesome as well!

Great Fathom Hands - Fantastic Quality

Have just completed my latest build. The pictures doesnt do them justice but the hands are fantastic. I used the hour and minute hands and whilst the pic doesnt show the chrome/silver, they are really good quality and am very happy.

Was my first purchase from LA from recommendation. I will be a regular customer going forward.

Hands Review

I did not replace my existing hour and min hand with these but i did with my sec arm. Overall, quite decent looking and it has the requirement I want. The lume is quite bright too.

Top Quality Every Time

I chose these hands to go with a new build I was working on, figuring they'd pair nicely with the dial and I was more than right. These hands are gorgeous. Lume is bright. All hands will definitely be purchased here from now on. Just great quality.

Superb Finish

Love the polished finish on this set of hands. The Red accent on the seconds hand compliments the Polished Red & Black Chapter Ring on the SKX013! The photos on the website don't do them justice imo!!!
I'm using the SKX013 case, along with a High Top Crystal and I have the Polished Chapter Ring (Black & Red), Red Sub styled Bezel & Bezel Insert and the Mother of Pearl Day Date Dial

Great Fathom Hands

Superb quality product, as always from LA. I wanted to achieve a classic, more formal interpretation of the Great Fathoms mod, These hands were a perfect match and I’m super happy with the result. Thanks again to Adriel for the amazing customer support!

The Great Fathom Hands

This review is my update/addition to my previous review prior to fitting the Great Fathom hands. As stated the service is superb and delivery and packaging is absolutely excellent. The hands are now fitted to my custom Seiko movement watch. The hands fit perfectly and the Lume is excellent and long lasting. -
((Please note the red seconds hand in the photos is not as the supplied seconds hand -unfortunately I damaged the Great Fathom seconds hand during fitting)).
So— Full marks all round. Highly recommended. Thank you.

Beautiful hands

Wonderful hands to go with a great LA dial!

Using this mod part for: SKX007

Fantastic quality

Only the hour and minute hands are pictured, due to user error. Beautiful quality, as long as a dog doesn't nudge you and cause you to bend one of them during installation.

+1000 LEVEL OF DETAILS ON THESE HANDS!!!!

I ordered 2 set hands on luciusattelier to get something I really want. Thes hands is made with superluminova. Much more luminous than other brands of watch using the same product. If you look really close to these hands you will see every detail. I will order much more for other project.

Looks great with meteorite dial

Just put them in yesterday, looks pairs great with the meteorite dial and the lume matches perfectly. High quality stuff as always.

Nice hands, great lume

Great hands. They fit nicely and look great. I love the subtle finish. The lume is excellent, and the hands themselves are also quite sturdy (I've used hands from other vendors that were more prone to bending)
