Quartz is the new sexy. With our laser-engraved VH31 quartz movement, it’s time to bring the beauty of quartz out from behind the dial and into the spotlight. Paired with an exhibition caseback, it adds a distinctive, eye-catching touch to your build — a subtle statement that celebrates precision and modern design. Choose from a selection of exclusive engraving motifs available on our website, or go fully custom with your own design. For personalized engravings, simply reach out through our contact form or live chat before placing your order, and we’ll work with you to create the perfect, one-of-a-kind movement for your watch.

The VH31 is a quartz movement from Seiko's Time Module Inc., combining the precision of quartz with the smooth, sweeping motion typically found in mechanical movements. Designed for those who appreciate the aesthetic of a traditional watch but prefer the reliability and low maintenance of quartz, the VH31 offers the best of both worlds.

Now you can use it in our 00:34AM case (or any NH case, actually) with our VH31 movement holder for NH case. Or even better, discover the AQ-1, the first VH31-native case for modding. Only 8.7mm thick !

Key Features:

- Smooth Sweeping Second Hand: Unlike most quartz movements that tick once per second, the VH31 features a second hand that sweeps smoothly, ticking four times per second (4 Hz), mimicking the fluid motion of an automatic watch.

- High Accuracy: With an accuracy of ±15 seconds per month, the VH31 ensures precise timekeeping, requiring minimal adjustment over time.

- Battery Life: Powered by an SR920SW battery, the VH31 offers a battery life of approximately 2 years, making it both efficient and long-lasting.

- Jewels: The movement includes 2 jewels, reducing friction and wear on key components, which enhances its durability and longevity.

- Energy-Saving Function: The VH31 features an energy-saving mode that can be activated when the crown is pulled out, further extending the battery life.
