Given that Bitcoin’s Blockheight is the new global timestamp – the GMT of the Interneti – and also given that men’s jewelry can be both fun and practical, it’s high time that we outline the technical specs and possible aesthetic designs for the first ever Blockheight Timepiece. (Where else would you find such ballsy balderdash ? Nowhere I tells ya.)
The basic premise is a high-accuracy automatic timepiece displaying simply hours and minutes with a digital readout for blockheight as the only complication.ii The hours and minutes will be displayed using traditional analog hands and powered by the highest accuracy automaticiii movement available – Zenith’s ZO 342 movement using a silicon oscillator running at 15 hertz or 108`000 vphiv – while the blockheight will be regulated in a triply redundant manner as follows :
This trio of signal emitters and receivers will update the blockheight onto the six- or seven-digit e-paper display using first the lowest energy frequency to ping the radio tower, geosynchronous satellite, or cell tower (in that order) once per minute. If no pong is received within 10 seconds then the timepiece proceeds to the next highest energy band and so on until blockheight data is received. The radio and cell towers communicate to a TRB node hosted outside of NATO jurisdiction and connected to at least 15 network peers ; the geosynchronous satellite hosts its own separate TRB node.
The entry-level sports watch, dubbed BT1, features an athletic 40mm case design based on the Patek Philippe Nautilus 5711viii and is available in rose gold or white gold case with rubber deployant strap and a clasp using the same “precious” metal as on the case.ix The luxury model, dubbed BT2, is a 40mm dress watch based on the Patek Philippe Sky Moon Tourbillon 6002x with hand-engraved case, crown, lugs, slide piece, hands, and fold-over clasp and crocodile strap.xi
Blockheight is displayed on both via a backlit e-paper screen. As the timepiece contains a battery, CR2032-sized coin cell will need to be charged or replaced once every… four centuries.xii
This is a living document and input from technically qualified persons will be considered. Thanks for reading.

- Did you know that this state of global affairs has already been the case for five-plus years ? Where have you been, man, living under a rock with the worms and ‘roaches ??
- Now this is a perpetual calendar! [↩]
- Why automatic movement and not quartz ? Because romance! The same romance that makes you light wax candles at dinner. It’s a thing. [↩]
- As seen on the latest Zenith Defy Lab timepiece, the ZO 342 movement has no balance pivots and no conventional spring so positional rate variation is very near zero. With only 6 degrees of maximum amplitude variation compared to 300+ in a conventional balance, the 32.15mm x 8.13mm movement is accurate to ± 0.5 seconds over 48 hours, or twice the precision of the lauded Seiko Spring Drive.
In-house movements, let’s face it, are overrated, and this boutique piece – like every other bit of hardware that Bitcoin is using to take over the world, from CPUs to power grids to paper and pens – is better served by using the best of the remnants of the decaying Empire than reinventing every last nut and bolt.

- The rubber deployant strap for the BT1 is based on that of the Oysterflex as seen on the Rolex Yachtmaster 116655. [↩]
As you’ll surely have noticed, there are only six e-paper digits displayed in line with the lower crown. That’s because the leading digit is displayed as a physically rotating Roman numeral in-line with the upper crown and beneath the “XII” hour marker on the BT2. A “III” is shown in the sketch for display purposes but a blank space would otherwise be shown until blockheight 1`000`000 sometime in the mid-2020s. [↩]
- Why both Patek-based designs ? Because they’re utterly gorgeous and really nail dat heirloom quality. [↩]
- Sum maffs :
A typical 2-inch [e-paper] module that integrates the display with an external timing controller requires 2.33 mA for 2.32 seconds to completely refresh the screen. That’s a daily power consumption of 32.43 mAs, or 59,191.32 mAs over five years. This is 8.5% of the nominal capacity of a single coin cell. If you only need to update part of the information on the display, even less energy is needed and e-paper displays consume no energy at all to maintain a static image.
As a conservative estimate, we specify our 2-inch e-paper modules to support at least 50,000 updates on an energy budget of 25% of a CR2032 coin cell. This takes into account that coin cells are normally warranted for 5 years, exhibit some leakage and that other components within the module draw some current. In theory, that’s an operating life of 22 years, based on the operating conditions described.
via PSD. Now figure that the screens on the BTs are only about 15 mm in width and 5 mm in height for a surface area of 75 mm² compared to the 1290.32 mm² of a perfectly square 2-inch e-paper screen. As such, the BT screens could be powered by a single CR2032 coin cell for 378 years! [↩]
