HKM-685139 Twosome Automatic Moon Phase Tourbillon

Refined Engineering, Uncompromising Detail

Tourbillon: The Heart of Precision

The tourbillon carriage rotates continuously to average out positional errors caused by gravity. Mounted within a lightweight titanium cage, this mechanism delivers a captivating visual ballet while improving rate stability. The intricate finishing on the bridge and escapement reflects the dedication invested in this movement.

Moon Phase: A Celestial Companion

At a glance, observe the current phase of the moon with a dedicated sub-dial. The polished disc, decorated with stars and a golden moon, advances discreetly every 24 hours. Accurate to within one day every 122 years, this complication marries romanticism with mechanical rigor, providing a functional and poetic addition to the dial.

Titanium Case: Strength Without Weight

Crafted from Grade 5 titanium, the 41 mm (1.61 in) case offers exceptional corrosion resistance and a featherlight feel on the wrist. At just 11 mm (0.43 in) thick, it slips comfortably under a cuff. The subtle brushed and polished surfaces reflect light with refined sophistication, while the hypoallergenic properties of titanium make it suitable for sensitive skin.

Exhibition Caseback: A Window to the Movement

The transparent caseback, fitted with a hardened mineral crystal, offers an unobstructed view of the automatic winding rotor, blued screws, and perlage finishing. Observing the tourbillon in motion from the reverse side becomes a private pleasure each time you take the watch off.

Water Resistance & Daily Durability

Rated at 30 meters (98 feet), the watch withstands accidental splashes, rain, and brief immersion. The screw-down crown and gasketed case construction ensure reliable protection. While not designed for swimming or diving, it handles the rigors of daily life with quiet resilience.

Bracelet & Clasp: Secure Comfort

A robust stainless steel bracelet (Seiko-sourced) integrates seamlessly with the titanium case, offering durability and a classic aesthetic. The folding buckle clasp with safety lock ensures the watch stays firmly in place, while the micro-adjustment feature allows a tailored fit for wrists of various sizes.

Why the HKM-685139 Stands Apart

Tourbillon at Accessible Value: Traditional tourbillon timepieces often command a significant premium. This model integrates a beautifully finished tourbillon without compromising on quality, making haute horology attainable.
Lightweight Daily Wear: Titanium reduces wrist fatigue dramatically compared to stainless steel. You enjoy the presence of a 41 mm watch with the comfort of a much smaller piece.
Dual Complications in Harmony: The tourbillon and moon phase are arranged to balance the dial aesthetically, preventing clutter while offering rich visual interest from multiple angles.
Scratch-Resistant Crystal: The mirror film surface offers excellent clarity and guards against everyday scratches, maintaining the dial's legibility for years.

Frequently Asked Questions

How do I set the moon phase correctly?
Pull the crown to the second position and rotate clockwise to advance the moon disc. Align the full moon with the center of the display window, then consult a lunar calendar to set the current phase. The moon phase advances once every 24 hours; minor adjustments every few months keep it accurate.
Is the tourbillon visible during normal wear?
Yes. The dial cut-out at 6 o'clock frames the tourbillon carriage, allowing you to appreciate its rotation at a glance. The exhibition caseback further reveals the mechanism from behind.
Can I swim or shower with this watch?
The 30M (98 ft) water resistance rating is suitable for splashes, rain, and hand washing. It is not recommended for swimming, diving, or prolonged submersion. Avoid operating the crown when the watch is wet.
What type of movement does it use?
The watch houses an automatic mechanical movement produced in Taiwan, featuring 21 jewels and a frequency of 21,600 vibrations per hour. The self-winding mechanism builds power reserve through wrist motion, with a manual winding option available via the crown.
How should I care for the titanium case?
Titanium is highly resistant to corrosion but can develop surface scratches over time. Wipe the case with a soft microfiber cloth after wear. Avoid contact with abrasive surfaces. A gentle soap solution and soft brush can be used for occasional deeper cleaning.

Great buy

I absolutely love these Amazon Essentials Belice Ballet Flats! They are so comfortable right out of the box and fit my feet perfectly. I can wear them all day without my feet hurting, which is hard to find with flats sometimes. They’re also really cute and go with almost everything I wear. I find myself reaching for them all the time because they’re both comfy and pretty. Definitely a great everyday shoe, especially for the price!

Loooove these shoes!

I have these in several colors, and they’ve become a true staple in my wardrobe. The Amazon Essentials Women's Belice Comfortable Slip-On Ballet Flats are exactly what I look for in an everyday shoe—simple, versatile, and comfortable right out of the box. The slip-on design makes them super convenient for busy days, and they pair effortlessly with everything from jeans to dresses to work outfits. They’re lightweight but still feel supportive enough for all-day wear, and I appreciate that they don’t require a break-in period. The fit is generally true to size, and the variety of colors makes it easy to stock up and rotate depending on the outfit. Overall, these are reliable, easy-to-wear flats that offer great value for the price. Not flashy, just consistently comfortable and practical—which is exactly why I keep coming back to them.
