Huaqiangbei had nearly all the pieces Allen wanted, so he began by buying a watch physique with no buttons or dials for 420 yuan, primarily as a result of it had the display. The battery price solely 15 yuan, however getting his arms on the logic board proved far more tough. After exploring the markets and knocking on a couple of doorways, he lastly discovered a dependable working board, which one in every of his connections confirmed had all the requisite seals of authenticity for 350 yuan.

So it was lastly time to get began on the reverse engineering. That started with sending a reference mannequin of the watch physique to a neighborhood firm for a 3D scan, which took considerably longer than deliberate and price him 340 yuan. Nevertheless, the final word end result was a mannequin that was correct to inside 50 microns. That was fed right into a machine that lower out a complete new aluminum case utilizing a NestWorks C500 desktop CNC mill, which was stored cool by a water mist system whereas in operation. Slicing the casing required two passes: a tough preliminary move to take away the vast majority of the fabric, then a second, extra correct move with angled slots and holes to accommodate the band attachments and buttons. Thread milling allowed him to create small, ultra-precise holes with out resorting to fussy tapping.

Simply when all the pieces was going effectively, a hitch arose: a handful of the holes had been drilled too deeply, forcing Allen to start out over. Then, to make issues worse, his customs cargo was delayed owing to what seemed to be labelling issues on the bins. It’s time for his total crew to roll up their sleeves and go to work.

Your common DIYer would have needed to battle with the handcrafted items to get them to suit correctly.

Meeting befell at residence, the place a little bit warmth helped launch the adhesive holding the brand new battery and glass in place; a microscope got here in very useful for messing with these tiny flex connections which are so simply broken. The logic board was put in first, wrapped across the within the watch by the battery, adopted by the display, which was put in with optically clear sticky goo; he heated it and pressed it firmly to make sure it was appropriately put in. Later, the perimeters, buttons, springs, and seal gasket arrived to finish the rebuild. The buttons had been a little bit robust to suit into the brand new case and required some snipping.

When it got here time to place the watch by means of its paces, he was happy to see that all the pieces labored because it ought to, together with the microphone and speaker, GPS, coronary heart price sensor, and so forth, with the show displaying up rapidly after a cost and the machine connecting up with none points. There have been a couple of minor flaws from the components swap, however total, the watch appeared nice and operated effectively.
