One of the largest and most anticipated tech tradeshows of the year has finally arrived in CES 2015 and it's collided with one of the biggest trends expected to explode this year: smartwatches.

While we still expect more smartwatches to appear at Mobile World Congress in March, along with the Apple Watch appearing early this year, there's plenty to see at CES.

We've been checking out the best the show has to offer your wrist and have compiled everything in one place so you can decide what's going to make a difference this year.

Garmin announced three additions to its wearable range at CES 2015, including the Vivoactive that puts the company firmly in the smartwatch arena.

The Vivoactive builds on the Vivofit sports band, offering users some lifestyle tracking functions, but it adds built-in GPS and connects to your smartphone for notifications.

It will work with Android and iOS devices as it uses Bluetooth Smart and the Garmin Connect Mobile app. You'll be able to track running, cycling, winning and golf, as well as steps, sleep and workouts, while also keep an eye on calls, messages, emails and calendar notifications.

The Garmin Vivoactive is up for pre-order in the US, costing $249.99, but there has been no word on UK pricing just yet.

Guess is one of the first fashion companies to hop on the smartwatch bandwagon with Guess Connect, which has come about through a partnership with Martian Watches.

Martian Watches will be keeping the smart side of things updated and the watch, which is based on the Guess Rigor, will allow users to customise it using the iOS or Android app.

There is a notifications window at the bottom of the watch face, but you'll also find a mic and speaker, which means you'll be able to use your watch to issue voice commands and take calls.

Kronos is a Swiss company that started in January 2013 specialising in wearables and it has unveiled a whole line of wearables at CES 2015, with ZeWatch2 at the forefront.

Kronoz

The ZeWatch2 is a Bluetooth connected wrist-worn device that tracks activity, delivers notifications and offers an integrated speaker. It will notify you when you have an incoming call and allow you to answer it, as well as let you read your messages and other alerts, with each appearing on the screen along with a vibrating alert.

The Kronoz ZeWatch2 will also monitor and analyse your sleep cycles. It works with iOS and Android and is available now for €79 from Kronoz.

Lenovo announced a new fitness band at CES 2015 called the Vibe Band VB10, which is a Bluetooth 4.0 LE connected device that has an E Ink display.

The Vibe Band VB10 will display notifications for calls, texts, social media and more, allowing for 150 characters on the display at any one time.

It will work with iOS and Android smartphones, claims a seven-day battery life despite being always on, and it weighs just 30g, while also offering water resistance.

The Vibe Band will come in black, silver and gold, with various straps available and you'll be able to buy it from April for $89.

This Bluetooth connected bracelet is pretty special. LookSee brings style and wearables notifications together with a wrap-around E Ink display meaning a super low power consumption.

LookSee

The screen allows for black, grey and white to be displayed and it will show off text, photos, clock faces, maps, QR codes and boarding passes.

On a single charge it's claimed the bracelet will last a year, or with an update every ten minutes it will keep going for two months. You can register your interest now on the LookSee website for a release date and pricing.

LG confirmed to Android Central at CES in Las Vegas that it has created a variation of its G Watch R for Audi running a variation of the webOS operating system making it the first of its kind. This watch will be able to support and control in-car systems thanks to software from LG. The watch itself looks like a more premium version of the G Watch R featuring a metallic finish on the face and a leather strap.

Few other details were given but presumably the watch will be available for those that own Audis as well as those buying one for the first time.

Martian is a US company that you may not have heard of, except for if you read about the Guess smartwatch at the beginning of this feature.

Martian

They're taking a unique stance on smartwatches, finding a blend between the digital and the analogue. The Passport, Victory and G2G were already available but they now have a firmware update.

The Martian watches feature a full analogue face with a digital screen along the bottom. This connects to iPhone and Android mobiles and can be used as a notification centre while also being voice controlled for texting on the move, answering calls and even triggering the phone's camera.

Mio, one of the first companies to put a heart rate monitor on wrists, has announced its second generation Alpha 2 and Fuse wearables at CES 2015.

Mio

The Mio Alpha 2 features a heart rate monitor and connects via Bluetooth to Android mobiles and iPhones to offer HR data right into the app users already have on their phones. The Mio Fuse is a sport activity tracking wrist band that also offers EKG-quality heart rate monitoring. It can transmit data via Bluetooth of ANT+.

Both devices are shock resistant and water resistant to 30 metres. Pricing and release dates have not been announced.

The Montblanc e-Strap screen sits on the underside of the wrist where the clasp would normally be. It effectively offers a second face for more information on your wrist but it means you can continue wearing an attractive watch without the need to make the jump to pure digital smartwatch.

Montblanc

The e-Strap is made from leather with a carbon fibre texture and features a 0.9-inch 128 x 36 resolution OLED touchscreen in a unit made from diamond-like carbon-coated steel. This will come in a selection of sizes and colours and it is both splash and shock resistant.

The e-Strap will track the wearer's daily activity and it offers a screen and vibration for phone notifications via Bluetooth 4.0, including calls, messages, calendars, social media, reminders, plus you can use it to control the phone's music player or camera.

MOTA, after a successful crowd-funding run, will begin shipping its SmartRing wearable in June 2015. The SmartRing features a touchscreen and connects to your smartphone for discreet vibrating notifications.

Mota

From calls and texts, to specific person alerts, the ring will display it all so you don't need to take your phone out, unless you have to. The idea is to be super discreet without replacing your watch. How well the battery does on a device of this size remains to be seen but after a popular crowd funding it's certainly going to get a lot of attention, especially at that $99 price which is about £63.

MOTA SmartWatch G2 Lite is what we'd imagine the lovechild of a Samsung Gear Fit and Nike FuelBand would look like. It looks sleek with a low power OLED screen and should sound good too with integrated speakers, plus there's a mic for voice controls. It connects via Bluetooth 3.0 and should last for up to 72 hours on standby, 3 hours talktime and charges in 2 hours, says MOTA. All very impressive for the $80 price which is about £52.

The MOTA SmartGlass is the companies answer to Google Glass. It features a 720p camera for recording and a small screen similar to Google's creation – it's in beta testing right now with few other details.

Two new smartwatches have been added to the Omate line, announced at CES 2015. The Omate Racer and Omate Roma work with both Android and iOS phones using Bluetooth 4.0 LE.

Omate

The Roma is more about elegance while the Racer is aimed at the sporting types. Both feature an always-on display and MediaTek MT2502 processor. The Racer can be pre-ordered from 6 January from $99 and the Roma for $129 from 31 January.

Polar, already a well known sports watch brand, now offers an activity tracking option. The new Polar A300 is far cheaper than a GPS-packing watch, but it still manages to track daily steps using the built-in pedometer. It will also work with a heart rate monitor for even more data.

Polar

The unit itself can be removed from the strap for wearing or carrying on the person anywhere, in case you don't like the look - which is almost identical to the Polar V800. The A300 is weatherproof, offerings training guidance and comes in black, white or pink for $140 or $180 with the heart rate monitor chest strap - it will be available from February.

Sony has used CES 2015 to launch a number of designer SmartBand fitness tracker, as well as a stainless steel version of its SmartWatch 3, which originally launched at IFA 2014.

The stainless steel SmartWatch 3 will feature the same specs as the original SmartWatch 3 including processing power, display, software and built-in GPS, but it will now come encased in stainless steel.

The SmartBand fitness tracker on the other hand was launched at CES 2014, and this year's show sees Sony collaborate with designers including Jack Vartanian, Ted Baker and Roxy to introduce accessories and special versions of the band.

Sony also launched a new gadget it is calling SmartEyeglass Attach!, set to take on Google Glass as a single lens display module for attaching to regular glasses.

Swarovski has teamed up with Misfit in a bid to make wearables sexy with the Swarovski Shine jewellery collection.

Swarovski

Aimed at women, the Swarovski Shine collection embeds the tech within the Misfit Shine activity and sleep tracker within a giant crystal, which is then compatible with nine pieces of jewellery including pendants, watch bands and bracelets.

Just like the Misfit Shine, the Swarovski Shine will measure steps, calories consumed, distant and sleep quality, wirelessly syncing with the Misfit app on your smartphone. The Swarovski Shine collection will be available as single products starting at $69.99 or in three sets starting at $169.99 and pre-orders are open now in the US.

Withings has updated it Activité with the latest Activité Pop, out now in the US where it will sell for $150, despite being essentially the same as the original watch which cost $450.

The difference is that the Pop is made with less expensive materials making it affordable - but it still looks great compared to many smartwatches.

The Activité Pop uses an analogue face to show the time and the user's daily step count. It's a really attractive way of tracking health that remains pretty unique and is waterproof to 30-metres.
