Apple Watch Sport, 42 mmApple explains that the Apple Watch Sport is "an incredibly accurate timepiece, an intimate and immediate communication device and a groundbreaking health and fitness companion" that is required to be paired with an also carried iPhone 5 or newer for most functions.

All Apple Watch devices are controlled with a "Digital Crown" and the Retina caliber displays include "Force Touch" capability that can differentiate between a light tap and a heavier press for more navigational possibilities.

Battery life is an Apple estimated "up to 18 hours" overall, but more specifically "up to 3 hours" of talk time, "up to 6.5 hours" of audio playback or working out, "up to 48 hours" of use as a watch (using it 20 seconds per hour), and "up to 72 hours" of low power "Power Reserve" usage. It charges via a custom inductive charger with MagSafe capability which is made of plastic for this model rather than metal like the higher-end models.

Designed as a more budget friendly option compared to the "regular" and "Edition" models, this particular original Apple Watch, the "Sport" model in the 42 mm size, features a 312x390 display with "strengthened, lightweight Ion-X glass" packed in a 7000 series anodized aluminum housing with a composite back and "hard coated optical polymer lenses" that connect to the charger.

There originally were five specific configurations of this Apple Watch Sport that vary by finish and band. With a silver colored aluminum body, Apple originally offered a white (pictured, left), blue, lime green, or pink "fluoroelastomer" rubber "Sport Band" and with a dark "Space Gray" aluminum housing, Apple originally offered, and continues to offer, a black "fluoroelastomer" rubber "Sport Band" (pictured, right).

On September 9, 2015, Apple discontinued three options -- the silver colored aluminum body with blue, green, and pink Sport Bands -- and introduced four new ones -- a silver colored aluminum body with orange or blue Sport Bands (the new blue option is a bit more aqua colored) and a Rose Gold colored aluminum body with a beige "Stone" Sport Band and a gold colored aluminum body with an "Midnight Blue" Sport Band.

On January 4, 2016, Apple introduced two "special" models for Chinese New Year available in China, Hong Kong, Taiwan, Singapore, and Malaysia. These models are offered with either a silver colored or gold colored aluminum body and a red Sport Band and were sold until February 22, 2016.

Finally, on March 21, 2016, Apple discontinued two more options -- the silver colored aluminum body with Blue and Orange Sport Bands -- and introduced seven new ones. These new options include a silver colored aluminum body with Yellow, Apricot, and Royal Blue Sport Bands; a silver colored aluminum body with a "Scuba Blue" (Aquamarine Outside, Green Inside) Woven Nylon band; a Rose Gold aluminum body with a Royal Blue Woven Nylon band; a Gold aluminum body with a Gold/Royal Blue Woven Nylon band; and a Space Gray aluminum body with a Black Woven Nylon band.

It was discontinued altogether on September 7, 2016.

March 9, 2015* September 7, 2016
Details: The "Introduction Date" refers to the date a model was introduced via press release. The "Discontinued Date" refers to the date a model either was replaced by a subsequent system or production otherwise ended.

*This device first was revealed as a demonstration on September 9, 2014, but with limited specifics, "introduced" in more detail on March 9, 2015, became available for pre-order on April 10, 2015, and actually was available as a product on April 24, 2015. On September 9, 2015, Apple discontinued three options and introduced four new ones.

On January 4, 2016, Apple introduced two "special" models for Chinese New Year in China, Hong Kong, Taiwan, Singapore, and Malaysia. These models were sold until February 22, 2016.

Finally, on March 21, 2016, Apple discontinued two options and introduced seven new ones.
520 MHz Apple S1*
Details: *Apple provides no information on the processor used in the Apple Watch beyond that it is an "entire computer system on a single chip" encapsulated in resin. Apple refers to this processor as the "S1". However, third-party analysis from Chipworks, determined that the processor is a Samsung-produced single core 32-bit 28 nm APL0778 processor that runs around 520 MHz.
512 MB 8 GB*
Details: *Apple makes no official mention of storage capacity. However, as first reported by 9to5Mac, the Apple Watch models all have 8 GB of storage capacity, 2 GB of which can be used for music storage and 75 MB of which can be used for photo storage independently from music and photos stored on a paired iPhone.
200* 100*
Details: *Apple does not provide an estimate of song and photo capacity, but based on the 2 GB of storage for music and 75 MB of storage for photos, 200 songs and 100 photos is a reasonable estimate.
Watch Apple Watch Sport (42 mm)
Details: This Apple Watch Sport has a 42 mm form factor and uses a 7000 series anodized aluminum housing.
Aluminum* Digital Crown
Details: *The Apple Watch Sport uses a 7000 series anodized aluminum housing. Originally, it was available with a silver colored finish or a dark "Space Gray" finish, but on September 9, 2015, Apple added a Yellow Gold and Rose Gold colored finish option, as well.
1.65" OLED* 312x390
Details: *The entire face of the watch contains a roughly 1.65" OLED, but this is not all viewable area. Apple's Developer Guidelines for the Apple Watch specify that all 42 mm models have a viewable display resolution of 312-by-390 pixels. The Apple Watch Sport display is covered by "strengthened, lightweight Ion-X glass."
802.11b/g 4.0
Details: The Apple Watch Sport has built-in support for 802.11b/g and Bluetooth 4.0 to "pair seamlessly with your iPhone."
Lithium Ion* 3-18 Hours*
Details: *Apple provides no details on the type of battery in the Apple Watch Sport, but it is a proprietary Lithium Ion. Apple reports that the device provides "up to 18 hours" of battery life which includes "90 time checks, 90 notifications, 45 minutes of app use and a 30 minute workout with music playback from Apple Watch via Bluetooth." Battery life for other uses varies -- reportedly "up to 3 hours" of talk time, "up to 6.5 hours" of audio playback or working out, "up to 48 hours" of use as a watch (using it 20 seconds per hour), and "up to 72 hours" of low power "Power Reserve" usage. Apple also notes that the 42 mm Apple Watch models "typically experience longer battery life" so it would be safe to assume that they have a slightly larger battery as well. In fact, as reported by AnandTech, the 42 mm Apple Watch models specifically have a 3.78 V 0.93 Watt Hour (246 mA H) battery, which is larger than the 0.78 Watt Hour (205 mA H) battery in the 38 mm models.
MJ3N2LL/A* Watch Sport 42mm
Details: *MJ3N2LL/A refers to the 42 mm Aluminum Apple Watch Sport with a silver colored finish paired with a white rubber "Sport Band." Also with a silver colored finish, but paired with a blue, lime green, or pink rubber band, the order numbers are MJ3Q2LL/A, MJ3P2LL/A, and MJ3R2LL/A, respectively. With a dark "Space Gray" finish paired with a black rubber band, the order number is MJ3T2LL/A.

For the four new options added September 9, 2015, the silver colored finish with an orange and blue (which is a bit more aqua colored than the model replaced) Sport Band are MLC42LL/A and MLC52LL/A, respectively; the Rose Gold colored finish with a beige colored "Stone" Sport Band is MLC62LL/A, and the Gold colored finish with an "Midnight Blue" Sport Band is MLC72LL/A.

The "special" Chinese New Year models -- introduced January 4, 2016 and discontinued February 22, 2016 -- have different order numbers in different countries, but in Singapore, they are MMEE2ZA/A and MMED2ZA/A, with a gold colored aluminum finish and a silver colored aluminum finish, respectively. Both of these Chinese New Year models have a red rubber "Sport Band."

For the seven new options introduced March 21, 2016, the silver colored finish with Yellow, Apricot, and Royal Blue Sport Bands are MMFE2LL/A, MMFL2LL/A, and MMFM2LL/A, respectively; the silver colored finish with a "Scuba Blue" (Aquamarine Outside, Green Inside) Woven Nylon band is MMFN2LL/A; the Rose Gold aluminum finish with a Royal Blue Woven Nylon band is MMFP2LL/A; the Gold aluminum body with a Gold/Royal Blue Woven Nylon band is MMFQ2LL/A; and the Space Gray aluminum body with a Black Woven Nylon band is MMFR2LL/A.
