Alpinestars - Supertech SM-10 Dyno Helmet
With years of development, Alpinestars has raised the bar in the high-end motocross helmet market with the all new Supertech SM-10 motocross helmet. Featuring carbon fiber construction and innovative features that are exclusive to Alpinestars such as the A-head interior liner for supurb fit, four different EPS densities and a MIPS rotational layer that offers a high level of impact absorption. MIPS is a proven safety system that helps reduce the rotational movement in the helmet by absorbing and redirecting the energy/forces that would otherwise transmitted to the brain.
The SM-10 helmet is filled with new technology such as Alpinestars patented Visor system that has been developed to provide the right level of resistance to release when needed from impacts in any direction. The interior of the SM-10 helmet has been designed with maximum ventilation in mind. An interior air network channels incoming air through the helmet to keep rider's head cool, while continuing to pull hot air away and through the large exhaust vents.
The helmet has been designed for riders that wear neck braces and those that don't The bottom area of the helmet is raised to clear rider's collarbone area as much as possible. This gives dirt bike riders confidence while riding on the track, trail, or anywhere else. The SM-10 is also hydration system ready, as it has a channel inside the chin bar specifically for hydration tubes.
BTO Sports is your Alpinestars SM-10 Helmet source with all the colors and sizes you need.
Features:
- A-Head: Patented system allows easy adjustment of the angle that the helmet sits on your head. MIPS system is also included in the helmet.
- Visor: Patented system has been developed to provide the right level of resistance to release when needed with impacts from any direction. The visor system is light weight.
- Collarbone: The bottom side of the helmet is raised to clear the collarbone as much as possible for riders who choose not to wear a neck brace system. In addition, the bottom trim is soft on the collarbone area.
- Mouthpiece: To maintain strength of the mouthpiece, a radial ridge has been incorporated which assures complete strength to the front of the helmet.
- Maximum Ventilation: The Interior air network channeling has extremely high ventilation values made possible by the airflow design and the location of all air intakes and outlets

Classy fully automatic watch - lots of bling too
Watches with a mechanical movement are becoming more mainstream despite the impact of smart watches and quartz movement timepieces. With a pure mechanical watch, there are no concerns about battery charge so when you pick it up from the nightstand, all you would have to do is give the stem a twist to wind the main spring, reset the time and off you go - and that's only if it has stopped. If it hasn't stopped (it won't if you wear it every day or have a watch winder) you strap it on and you are all set.
I gave this watch my regular accuracy test set against a clock linked to the atomic time source. To my great surprise, it was as accurate as one of my much more expensive mechanical watches (how much more expensive? This watch costs about the same as the sales tax on the most pricy watch in the closet !!)
I use the included watch bracelet tool to remove a link from the watch to get a proper fit. Including the tool in the box saves you the $10 plus fee a jeweler might charge you to make the adjustment - very cool. And you probably will need to remove at least one link - some may need to remove two - since the bracelet has a generous size. Speaking of the bracelet, it's beautiful. I wore the watch today to church and a friend said it had "heavy duty bling" ... But she did say she thought it was beautiful and I concur. Finally, The way the bracelet clasp works is reminiscent of a Longines bracelet i have and that spells quality to me.
The dial is black with chrome shiny minute markers so visibility in good light is excellent. I do not detect any glow in the dark markings on the hands or the minute markers - factor that in for your purchase decision.
I see this watch as serving as your "good" watch for business wear, to don for a meal at a fancy restaurant or for that big date night. I think it has a classic look that (despite the bling of the bracelet) is conservative enough for anyone and any business situation.The only place I wouldn't wear it is to the beach or the gym despite the fact that it has claimed that it is waterproof to depths you probably will never experience.
Accurate, beautiful, real quality that translates to good value and capable of being almost anyone's "good" watch.

Es muy elegante
Color: 3316：white band white dial
The OUPINKE Automatic Two-Tone Skeleton Watch is a stylish timepiece that blends luxury design with mechanical craftsmanship. Its gold and silver stainless steel construction gives it an elegant, premium look suitable for both formal and casual occasions.
Design & Appearance:
This watch stands out with its two-tone bracelet and gold-accented bezel, creating a bold and sophisticated aesthetic. The dial features crystal-style hour markers, multiple subdials, and a visible skeleton window at the bottom that showcases the internal movement. These details add a high-end feel often associated with more expensive watches.
Movement & Performance:
It uses an automatic mechanical movement, which means it winds itself through the motion of your wrist—no battery required. This is a major advantage for watch enthusiasts who appreciate traditional watchmaking. The watch also includes useful calendar features such as day, date, and month indicators.
Build Quality:
The stainless steel case and bracelet feel solid and durable. The polished finish enhances its luxury appeal, although like most polished watches, it may show fingerprints or small scratches over time.
Comfort:
Despite its robust design, the watch is comfortable to wear. The bracelet is well-balanced, and the clasp keeps it secure on the wrist.

Exceptional quality
I have only had the watch for a few days, but Oupinke watches are very high quality. It keeps time very well and serves as an attention grabber. Great value for the money. It isn't easy to determine where it was made, but it is a Chinese company. Don't stop there with preconceived ideas about cheap products and low quality from China. These watches are exceptional, high-end, and dedicated to creating a brand that endures and stands for quality, rather than simply turning a profit. I would put this watch against those that cost 3-4 times as much. If you are a watch enthusiast, they are worth adding to your collection.
