Meridiano, Antick Design & AndoAndoAndo present the first 38mm case for VH31 quartz movements

For years, the Seiko modding community had no options for cases thinner than 11mm. But the wait is finally over! We've teamed up with the incredibly talented Antick Design to create a sweet, VERY thin (8.7mm!), and beautiful 38mm case for VH quartz movement.

And to fit this case, we also sell a very cool selection of quartz hands and VH31 movements !

We now offer an exhibition caseback for the AQ-1 case. Quartz is the new sexy, so click here to discover this amazing item!

Key Benefits of quartz movements for modding

• Affordability: A more accessible entry into modding: less pressure, more creativity.
• Battery-powered (~2 years): Say goodbye to the hassle of winding and frequent adjustments: perfect for daily wear.
• Accuracy (+/- 15 seconds per month): More than twice the accuracy of an automatic, so you can rely on your watch every day.
• Compatible with NH3x dials (28.5mm): You can still use your favorite dials from the modding community.
• Thinner cases: We’ve nailed it! This case is thinner and sleeker than ever before!

If you're looking to explore modding without the intricacies of mechanical movements, this quartz case is the ideal gateway. It’s a fun, stress-free way to create something personal and unique.

The Case

Our case is made entirely of 316L stainless steel, offering superior hardness and durability. Unlike other grades, 316 stainless steel is highly corrosion-resistant in acidic, alkaline, and chloride environments (including pool and sea water) and is 100% rustproof. It's also commonly used in the medical industry because its hard surface prevents the adherence and survival of microbes.

The case features a stunning and subtle mix of brushed and polished finishes.

The 5 ATM water rating means it can withstand water pressure up to a depth of 50 meters before sustaining water damage. A 5 ATM watch can be worn while swimming for brief periods, in the shower, or in the rain, but should never be used for water sports of any kind. Take special care with warm to hot water, as it can ruin the seal that prevents water from entering the watch. Hot water can also cause condensation inside the watch.

The Crown

Despite its compact size, the crown is elegant and designed to be easy to manipulate.

The Glass

We chose a beautiful and durable flat sapphire crystal with an AR coating so you can fully enjoy the beauty of your dial.

Compatibility

The case is compatible with a wide range of quartz movements, including the entire TMI VH series (VH31, VH60, VH61, VH63, VH65, VH67, VH68, VH83, VH88), many TMI VD series movements (VD70, VD72, VD74, VD75, VD76, VD77, VD78, VD79, VD84, VD85, VD86, VD87), the Miyota 2115, TMI PC39, and several others we haven’t tested yet!
