A&D FZ-523 - 520g x 0.001g Precision Balance
The A&D Fortis FZ-523 is a precision balance built around the philosophy of paying for what matters: reliable, accurate weighing without compromise. Featuring A&D's proven Compact Super Hybrid Sensor (C-SHS) technology, the Fortis delivers fast ~1-second stabilization with outstanding repeatability in a compact footprint smaller than an A4 sheet of paper.
One-touch internal calibration ensures the accuracy of the balance at any time: after relocation, temperature changes, or environmental fluctuation, with no special skills or external weights required. The Fortis also features A&D's patented Impact Shock Detection (ISD) system, which provides real-time feedback to prevent damage to the weight sensor, and a shock logging function that records up to 50 adverse impact events with timestamps for later inspection.
The clearly visible reverse-backlit LCD keeps readings easy to read in any lighting condition. A selectable response characteristic lets users trade faster weighing speed for higher display stability depending on the application. The anti-static, shatter-resistant breeze break with rotary sliding doors is easily detachable for cleaning and features a built-in level meter for accurate sample placement.
User Access Control (UAC) with password protection and user rights management ensures accountability in regulated laboratory environments. GLP/GMP/GCP/ISO compliant output with date, time, ID, and serial number meets documentation requirements across all industries.
Features:
- Internal calibration with one-touch operation, no external weights required
- Compact Super Hybrid Sensor (C-SHS) for fast, accurate weighing in a small footprint
- Impact Shock Detection (ISD) with shock logging (up to 50 events with timestamp) to protect the weight sensor
- Selectable response characteristics to balance speed and display stability
- Anti-static, shatter-resistant breeze break with rotary sliding doors, easily detachable for cleaning
- Counting mode with Automatic Counting Accuracy Improvement (ACAI) for high-accuracy piece counting
- Comparator function with buzzer for intuitive, error-free check weighing

- Animal weighing (average & hold) function for weighing moving objects
- Statistical calculation function (SCF) to facilitate the analysis of measurements
- Capacity indicator that lets you know the remaining capacity of the balance
- Density determination function (density kit sold separately)
- Underhook for below-balance weighing of density samples or magnetic materials
- User Access Control (UAC) with password lock and user rights management
- GLP/GMP/GCP/ISO compliant output with date, time, ID, and serial number

Beautifully simple
Color: Black/Digital/Green
My son has worn a smaller version of this watch for a few years. After trying a different brand lately, which broke way too easily, I found this one on Amazon listed as "Used - Very Good" condition. I received what appeared to be simply an open box item, otherwise it looked brand new.
This watch fits me really well, and is not clumsy on my wrist, it does not get in the way of everyday motions. For me, it's just the right size. It is also pretty intuitive to use and set the alarms, etc. It has 3 alarms, each with a different sound. It can be worn in the shower without issue, I have not tried a swimming pool, though. It feels tough and durable, as my son's has proven to be. I'm very happy with this purchase.
*** Update: I spent considerable time in swimming pools recently while wearing the watch. It's still as good as when I opened it. Still 5 stars.
*** Update 2: a year-and-a-half of wearing, and it is performing really well! All the buttons and words on the watch are still in very good shape and easy to read. I wear this every single day. I don't put it through the wringer every day. But, I did spend a full week sailing and snorkeling last summer in salt water with hours each day in the water. It still looks and works the same as the day I bought it.

Perfect for Training (Swimming) Purposes.... 5 Star for what it does as a training watch!
Color: Black/Yellow
This is already my 2nd TIMEX which I use for my swimming practices..
This one beats the older model (Timex 51931 Ironman Triathlon) with some interesting changes:
1) The larger digits on this model makes it easier to read the numbers (as some mentioned to do so when running) even when I am swimming, with a quick flick of the wrist at the turn, it's possible to see the minutes and the seconds.... The older model had smaller number, thus not making it possible to do this.
2) The navigation on this model became quite easier. It was already easy on the older model but this one included instructions on screen, such as NEXT, DONE, + or - in order to advance with your practices and training... Plus a chance to change the way you want to see the information of the your laps (Laps in the big digits and splits at the smaller one, or the oposite)
A Real nice add on by TIMEX.
3) A simple but effective wrist band "clip" (the tiny piece of strap that attachs the "extra" wrist band that is left after you put the clock on)
It has a piece of rubber on the inside that locks on at the wrist band and does not make it loose or even letting it go as some other watches do sometimes. This is more effective underwater I think, as it remains the way you set your wrist, as the older model I had did not quite held in place all the time.
4) Plenty of memory (100 laps is really a nice number), maybe more then most will need but, as a swimmer I use to count splits over 100m (or yards) with many laps during one training... It is quite usefull. I go easily on 10 to 15 laps of the memory in one training.
And with the date feature, that reminds when you did these times, it is quite usefull to keep track on the training with a spreadsheet, for instance... (as I do !)
5) A really big START/SPLIT buttom that is great to press when I am swimming laps and have to press myself at each turn at the pool.
Just perfect. Never a miss !
And the feature which was already at most of the models, of the repeat countdown, and the start of a chrono, or a repeat (what I use the most) in order race agains your average rhitym inside a certain time frame that you can set it up ! And of course the flix technology, which is very good to have it... Just flick your wrist (when you set it to ON) and it will show you at night all info that you need.
It is another great watch from TIMEX and it deserves a look, specially for the price. It is worth to pay a bit more if you are like me and uses a lot of the memory for the laps on swimming pool. Maybe for runners it can be quite a lot of memory, but the price difference is worth the change, for some of the options mentioned at this review.
This is a really good watch to have..
Will you definatelly like as we all are at these reviews.
:-) It deserves the 5 stars rating !

Great sports watch.
Color: Black/Yellow
I have to admit to being a bit of a watch fiend, having one for almost everything I do, but this is one of the most useful, yet cheaper priced items I've come to enjoy. When I work out I like as much information as I can get, so for running and biking I have a watch for that, but for swimming I needed a watch to help me count my laps and log my times. The Timex Ironman 100-lap watch does this quite well. I first got a Timex 50-Lap watch that I was able to find locally, but 50 laps is very limiting so when I found this watch for less money and a bigger face that had the lap/split time and lap number on the screen at all times I knew I had a great product. When you're finished with your laps just save your workout. The watch will then calculate some information like average lap time and best lap. I haven't completely messed with their data, but I think they average your times by throwing out the lap times that are the outliers, which is good for the accidental laps where you hit the wrong button, but it's not as great when you did a few sprint laps and they don't show up as your best time. If your best time isn't on there you can still recall it by going through each lap individually, but I think my sprint laps sometimes aren't listed as my best laps. I haven't messed with this feature much because it isn't important to me, and removing the outliers is good for looking at your actual pace. I have been able to push myself a bit more in the pool by having actual numbers to compare, which is very helpful. The other features on this watch I haven't used much, but for someone who can't afford a GPS watch and can use maps or a track this watch would be great for running or anything with laps or intervals.
It has up to 9 interval timers and once finished it can either stop or repeat the sequence. It can do what's called chrono at the end, where it just switches to the chronograph feature after your timer or interval timers are finished. Overall this is a great watch and for most people who enjoy doing anything with laps look no further.
