Ap­ple Watch

We take a look un­der the glass of the thin­ner, more pow­er­ful Ap­ple Watch Se­ries 4.

It’s Sum­mer, and that means three things: your warm socks are be­ing re­placed by thongs, the leaves are start­ing to turn green, and Ap­ple has just re­leased some new tech­nol­ogy.

This year we have an all-new Ap­ple Watch, fea­tur­ing a larger screen, a thin­ner de­sign and some smart new health fea­tures that are sure to help save lives. When it’s on some­one’s wrist, it looks so sim­i­lar to the pre­vi­ous Ap­ple Watches that you may not even give it a sec­ond look. But un­der­neath all that glass is some im­pres­sive new tech.

First, it’s got a faster, more ef­fi­cient chip, which has meant Ap­ple could make it slim­mer with­out re­duc­ing the bat­tery life. On the back of the watch you’ll find the optical heart-rate sen­sor that was in pre­vi­ous mod­els, along with a new elec­tri­cal ring. Paired with the metal in the dig­i­tal crown (the dial on the side of the watch), this forms a sim­ple elec­tro­car­dio­gram, or ECG ma­chine. It can record your heart beat and tell you whether you have car­diac prob­lems, so you can send the re­port to your doc­tor. That’s re­ally smart – al­though un­for­tu­nately the fea­ture is only ap­proved for use in the US so far, with global roll-outs still a way off.

On the front of the watch you’ll find a new, 30 per cent larger dis­play. It’s thin­ner and ex­tends right to the edge of the watch, curv­ing at the cor­ners. Just like be­fore, it’s wa­ter­proof down to depths of 50 me­tres and tracks work­outs, ac­tiv­ity and more.

SPEAK UPThis larger speaker is 50 per cent louder than the pre­vi­ous model and uses a sil­i­cone gas­ket to keep the wa­ter out.DIS­PLAYThis OLED dis­play ex­tends close to the edge of the glass, and the deep blacks blend right into the back­ground.HEART SEN­SORS CAS­INGThe cas­ing has been re­designed to be thin­ner and more ac­ces­si­ble, so your new Watch is eas­ier to re­pair if it breaks. The back panel con­tains the wire­less charg­ing ring, as well as the elec­tric ring that touches your wrist to en­able ECG mea­sure­ments.MOTHERBOARDThis sin­gle board holds al­most all the Watch’s ‘brains’. The S4 chip is twice as fast as the Ap­ple Watch Se­ries 3.DIG­I­TAL CROWNThis dial now clicks slightly as you turn it for im­proved feed­back, and you touch it to use the ECG sys­tem.PAD­DINGThis plate sits in­side the back case and ab­sorbs heat from the motherboard to stop it reach­ing your wrist.BAT­TERYThe bat­tery in the new Watch is ac­tu­ally smaller than the old one, but it still man­ages around 18 hours be­tween charges.TAPTIC EN­GINEThis lit­tle box uses mag­nets to cre­ate the feel­ing that the Watch is tap­ping you on your wrist when you get a no­ti­fi­ca­tion.
