This is something we’re pretty excited about. The stainless steel band was performing well, but we thought we could improve upon it. We tested titanium in parallel with stainless steel and concluded it’s worth the money to upgrade to this far superior material.
Weight: The entire watch assembly is nearly half the weight of the original: our previous weight of 12.5g has been reduced to 6.6g with the titanium band.
As far as we can tell, this means the CST-01 will be the world’s lightest watch, as well as the world’s thinnest.
It’s so light that a helium balloon can carry it! The watch on the left is one of the old prototypes with the steel band, the watch on the right is one of the new titanium samples:
Material Properties: Titanium has better "spring back,” (low elastic modulus) so it better keeps to its original, intended form after repeatedly wearing and removing the watch from your wrist. It is also less stiff, meaning it will be more compliant and comfortable when wearing.
Biocompatible: We are using “grade 5 titanium” (Ti6Al4V), which is extremely biocompatible. Those of you who were concerned about nickel allergies need not worry, as there is no nickel in the Titanium alloy we will be using. It’s the same alloy used in biomedical implants.
Badass: Grade 5 titanium is the stuff used on space shuttles, fighter jets, and satellites.
Titanium’s manufacturing properties have made the decision even easier. Titanium can be formed using ALL the same processes as stainless steel and does not incur any schedule slip. In fact, we have more forming and heat treating options available to us. Flextronics is working on forming tools at this very moment. Even the pre-production models we have feel incredible. They are so unbelievably light.
Brushed finish, PVD Coating: All models will have the same brushed finish. For the Nando Rossi and the Rose Gold editions, PVD coating works the same way as on titanium as stainless steel. (We’re waiting on brushed samples at the moment.)
All in all, we thought it was worth the extra cost for all the above benefits. It’s undeniably better in all categories.
In parallel with our work with Flextronics on the mass production units, we’re also been making samples of the watch and the base station for FCC, CE and other necessary certification for us to be able to ship worldwide.
These samples are for electrostatic discharge (ESD) testing (what happens when the watch and base station are exposed to incredibly high electric shocks), electromagnetic radiation emitted, and capacity to receive electromagnetic radiation.
The samples passed these tests with flying colors. A 4kV discharge does absolutely nothing to the watch or base station, 8kV resets the watch but causes no damage, and the watch emits basically no RF, which is not surprising given that it uses such a small amount of power and has no wireless capability. We will have no problem getting the required certification once the results are written up and submitted for approval.
Here’s a short video of those certification samples, the watch and base station changing time and going from 12-hour mode to 24-hour mode. This video shows the final method for setting the time also:
We did our tests at the Bay Area Compliance Lab. The anechoic chamber where the RF tests were done is completely sci-fi and incredible:
Sleepy Face Low Battery Indicator
We had fun coming up with an animation to communicate when the watch runs out of power. You will see this after a month of use if you let the battery drain all the way. Utilizing the segments available, we managed to create a pretty unique indicator:
Revised Shipping Schedule
We were hoping to start shipping the first batch of watches in late December, but now it looks like it will be late January before we could start shipping units. We are balancing the desire to ship as quickly as possible with the requirement that these watches will be robust and keep ticking when after being put through the paces. We will not sacrifice testing to get these out, and sometimes testing requires unforeseen refinement phases to address issues.
We know you want your rewards and we are doing everything we can to get them to you and have them be the best they can be.
We are working with Flextronics to outline another detailed plan based on what we know now and will get it out to you as a mini-update as soon as it's complete.
We estimated about 3 weeks for getting these models ready for CE and FCC testing in the last update. In parallel we were running our own electrical and hardware tests as we assembled those samples, These two items ended up taking about 3.5 weeks. The E Ink displays function as planned, with only one detail that required refinement in the battery-installation process. We were hoping that everything would be perfect, but were relieved that only one area required tweaking to get to best performance.
Those adjustments will get us a better performance in water resistance, something we know is a question from our backers.
We improved the geometry slightly and adjusted adhesives and assembly steps to better protect the battery from the elements. Once we got it right, it was bomb-proof in our initial tests. Check out his test where we threw a prototype from 12 feet high onto a concrete floor. (Although we are testing to these extreme conditions, please do not do these types of things to your watch!)
Here's another where we're bending it in a manner we do not recommend:
The physical adjustments were all released in CAD to Flextronics for the base station tooling and have been updated as of a week ago. This adjustment may have made an impact on tooling release: about 2 weeks.
We’ll be working with Flextronics to do all we can to expedite the next stage of the process, assembly line strategy is complex, and we’re asking a lot, there are so many new techniques and manufacturing processes in the CST-01 that it will require continued hard work. We’ll be continuing to have lengthy working sessions as we build this out and transfer some responsibilities over to Flextronics.
Batteries: Our custom batteries are arriving in a timely manner and are on schedule. We’re very happy to see their production is very much on target.
Base Station Electronics: All PCBs and components are on schedule with no delivery issues.
E Ink Sub-Assemblies: E Ink wanted to add a few weeks on their end for additional quality control and testing. We were expecting a batch of sub-assemblies by December 7. Now, the new delivery date is December 23-25. This puts us in a little bit of downtime as factories close down for Christmas, but we need to make sure these boards are perfect before the full order comes because there is no room for a mistake.
This Coming Month of Activities
- Over the next 2-3 weeks, we’ll be working closely with Flextronics on assembly-line design and delivery schedules.
- We’ll be sending out the reward survey shortly so that we can get all sizes, color, and delivery information from our backers.
- Finalizing the packaging design for shipping.
This month is going to be a busy one!
Dave, Jerry & the CST team
We’ve been getting a lot of similar questions, so we’ll be publishing a FAQ at the bottom of our updates in order to answer the majority of questions we receive.
Will you still be shipping in September? No. Our current schedule shows we’ll start to ship in late January.
What order will you be sending out watches? Can I get mine first? Rewards will be sent out in the order they were received. This is the only fair way to schedule it. We’re doing everything we can to get them out as soon as possible.
Has the survey gone out yet? Not yet. In the survey, you’ll be able to select your size(s), color(s), and submit your shipping information. We’re only allowed to send one survey, and as these types of data change every once in a while, we’re waiting until we absolutely need this info before sending you the survey. We’ll do everything we can to make sure you don't miss it, and we’ll post in the comments and issue an update when it does go out. If you’re concerned that you missed the survey, please look through the updates.
I would like to select my size, I am a... You’ll be able to do this in the survey that will be sent out when we need this information. The survey has not been sent out yet.
I would like to change my color to... See above
How can I change my shipping address? See above
Using the size chart, my wrist is just barely inside of (one size) and barely outside of (another size), which size do I choose? Using the size chart, you should choose the size where the band is inside the "size range" square (not outside). There’s no overlap in the sizing chart, and no space between sizes, so you should be inside of one of the areas. If it's really right on the line, and you don't know what to choose, we recommend the smaller size since the bands can be spread out slightly to accommodate larger wrists easier than they can be made smaller.
I'm a distributor/reseller/vlogger and would like a sample for… Production samples are not ready yet. The DVUs we do have are not final parts and are not ready for evaluation by suppliers or testers.
Where can I buy one? / I just found out about this Kickstarter and still want to pre-order one. / I would like to order additional colors. We’re still in the process of producing the CST-01, so they’re not shipping currently. If you’re interested in getting your name on the list for when we do ship, you can pre-order watches on our site: centralstandardtiming.com. Orders will be fulfilled in the order they were placed. Thanks for the interest!
I see that there’s one watch left at the $99 level, how do I get that one? The Kickstarter campaign has ended. That statement is a bug in the Kickstarter system that we’ve requested to have removed. We’ve been told that removing this statement is not possible, so you’ll just need to take our word that the campaign is over and there are no "early bird" rewards left. However, we’re still taking pre-orders on our site: centralstandardtiming.com.
