Much has been reported about Jony Ive’s departure from Apple and his decision to form his own design firm. The timeline of that decision may date back to the launch of the Apple Watch, with reduced input from Ive on newer projects in recent years.

Apple Watch is arguably the most Jony Ive product in Apple’s project portfolio, and with it comes an impact on health that could outlive any object shaped by Ive. Apple is hardly the first company to bring a smartwatch to market, but its mainstream appeal is very much a result of Jony Ive’s vision.

Design

That the Apple Watch borrows so heavily from the watch world that existed before it is no accident. It’s a decision traced directly to Jony Ive, a self-professed watch collector. As Hondinkee notes, “Apple consulted with seven independent experts in the field of horology during the development of Apple Watch,” including a horologist who studied timekeeping for over 40 years.

There’s no mistaking the Apple Watch for an ordinary watch, but Apple Watch draws more inspiration from mechanical watches than technical gadgets.

Where Apple Watch does rely on technology to achieve its purpose, the device clearly inspired the iPhone X more than three years before the phone’s release.

Apple Watch introduced features like Raise to Wake and Tap to Wake years before the iPhone X (and later the iPad Pro) adopted both to pull off an all-new design without a Home button. iPhone X was also the first to combine a stainless steel case with an OLED display, years after both came to Apple hardware with the first Apple Watch.

Jony even acknowledged that iPhones prior to the X model instantly looked dated due to the state-of-the-art hardware used in the Apple Watch. From the New Yorker profile in 2015:

Other features that started with the Apple Watch later came to iPhones introduced in the years that followed its development, including the excellent Haptic Engine that rivals nearly every competing smartphone vibration motor.

iPhones still haven’t matched modern watch levels of water resistance, but each phone model since iPhone 7 has touted some level of water resistance. In many ways including water resistance, Apple Watch has clearly been a materials playground for Apple’s industrial designers.

Health

And while iPhone captures a larger global market, Apple Watch has a deeply personal impact on many of the lives it reaches. Many credit the device with saving their lives in situations that the iPhone may have been ineffective due to the form factor.

Without hiding what Apple now calls a health guardian inside a cool watch with mainstream appeal, far fewer people would wear a device that’s capable of taking an electrocardiogram, tracking heart rate accurately in the background, sending alerts for high and low heart rates, and detecting hard falls —  even notifying emergency services and an emergency contact automatically.

The original Apple Watch wasn’t quite as sophisticated as newer models, but it created the formula of letting a watch be as true to its form as possible. Competing smartwatches have taken years longer to even try to catch up, and some smartwatch platforms have all but given up competing.

If the original Apple Watch was an absolute flop, we may have never seen the state-of-the-art technology brought to the masses with today’s hardware. The response it received clearly inspired future revisions, but only because Apple was on to something with the first. Before you consider features and benefits like notifications and staying connected, every customer considers the design and if the Apple Watch is something they even want to wear.

Ive even says that health was front of mind from the start of the watch design process, something only amplified by customers. From Hodinkee’s interview last year:

While the fashion of computers and phones will change from year to year, the impact of convincing customers to strap a sophisticated health monitor to their bodies without noticing it can last a lifetime for each customer.
