🔵[New item in May 2026, 10th anniversary of CURV] Bulova Curve 96A339|World's first curved chronograph x Monthly difference of ±5 seconds x 41mm evolution, favorite model with see-through blue dial

Featured models scheduled to be released on May 14, 2026 in the Bulova Curve (CURV) collection96A339will appear.
Curve was born in 2016 as an innovative collection equipped with "the world's first curved chronograph movement." The unprecedented design of curving the movement itself allows for a slim case and precision wearing comfort. The 96A339, which was released on the occasion of its 10th anniversary, has a smaller case size from 44mm to 41mm. This is a long-awaited updated model with an even better fit on the wrist.

The combination of see-through blue dial, sapphire glass, and see-through back creates both visual transparency and depth. The curved quartz movement can be seen through the case back - that's what makes this model stand out as a ``displayable movement'' rather than just a chronograph watch.

■ The reason for the “world’s first”—the innovation of the CURV movement

Normal chronograph watches have a flat movement, so the case has a certain thickness. The approach taken by Bulova's CURV was to curve the movement itself. By curving the movement to match the curve of your wrist, the entire case contours to your wrist, greatly reducing the discomfort you feel while wearing it.

This design, billed as a "world's first" when it was released 10 years ago, remains a unique and unique technology. While inheriting this technology, 96A339 has downsized the case diameter to 41mm, making it compatible with more arm circumferences and allowing more people to experience the ``CURV-like wearing comfort.''

■ 262KHz x Monthly difference ±5 seconds—The power of high precision quartz

The built-in high-precision quartz operates at an extremely high frequency of 262,144Hz. This frequency, which is approximately 8 times the frequency of a typical quartz watch, 32,768Hz, minimizes "accuracy fluctuations due to temperature changes" that are common with quartz watches. As a result, it has achieved a high accuracy of ±5 seconds per month, surpassing not only mechanical watches but also many quartz watches in terms of accuracy.

The movement visible through the see-through blue dial is proof of its high-precision design. The design, combined with the see-through case back, allows you to feel the inside of the watch from both the front and the back, and can be said to be a testament to Bulova's confidence in its movement.

■ 44mm→41mm——Beauty of proportions brought about by miniaturization

Changing the case diameter from 44mm to 41mm is only a 3mm difference in numbers, but it makes a big difference in how it feels when worn. The fit of a watch is determined by its balance with the wrist circumference, so by making the watch 3mm smaller, it can accommodate a wider arm circumference, making it the ``just right size'' for more people.

Weighing approximately 130g, it has a heavy feel typical of a metal bracelet, but when combined with the fit provided by the CURV movement, the weight actually feels like a comfortable presence. Suitable for arm circumferences up to 20.5cm, so it can accommodate a wide range of people, from those with narrow wrists to those with average wrists.

■ Recommended for these people

  • For those who have been curious about the Bulova Curve for a long time.
  • Those who were expecting a better fit with the downsizing of CURV to 41mm.
  • Those who are attracted to the world's first curved chronograph movement
  • Those who want to be particular about precision with high-precision quartz that has a monthly difference of ±5 seconds
  • Those who like the mechanical look of the see-through blue dial and see-through back.
  • Those who want to choose a color compared to 96A338/96K117
  • People who want to give a unique chronograph as a gift for anniversaries, birthdays, or promotions.

■ Buyer's comment

The first thing that struck me when I saw the 96A339 was that the size was downsized to 41mm, making it fit better in my hand. I have always loved the CURV model, but many of you must have felt that the 44mm lens had a little too much presence. With the update to 41mm, the proportions have become more suitable for everyday use. The combination of the see-through blue transparency and the curved movement peeking through the case back is unique. I think it is significant that this model was released on the occasion of the 10th anniversary.
