Review: my favorite clock ever TEN YEARS LATER AND STILL COUNTING DOWN! - I ordered one of these 3 years ago - it still works perfectly. I use it at home to time my yoga stretches. I just ordered a second one because I want one to take to the office. I am 62 years old, technology challenged, but this timer is simple enough for even me! May 14, 2019. When I go to this page it says: You purchased this item on September 11, 2009. I am 72 now, still using the timer for stretches. A couple of days it needed a new battery and of course I no longer have the instructions for reset, but I found them online at manualslib-dot-com. Tthere are many SEIKO stop watches and many that work similar to this model. Look for: SEIKO S056 Instructions -- S056 is a different model, but the reset instructions work for this model. Review: Good watches - Bought 2 for my husband for his work, he says they do the job and has no issues with them. Bought one at a time to be sure it was worth it and he requested the 2nd just like it. ## Features - 2-channel countdown timer - Each channel can be preset for up to 100 hours - Measurable up to 100 hours in 1/100 of a second - Split/lap time measurement - Store and recall of up to 100 split/lap times ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00065WZTS | | Best Sellers Rank | #465,266 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #190 in Stopwatches | | Brand Name | SEIKO | | Color | Black | | Customer Reviews | 3.9 3.9 out of 5 stars (53) | | Item Weight | 200 Grams | | Manufacturer | Seiko | | Manufacturer Part Number | S057 | | Material Type | Resin | | Model Number | S057 | | Number of settings | 5 | | UPC | 818443000774 | | Unit Count | 1.00 Count | ## Product Details - **Brand:** SEIKO - **Color:** Black - **Item Weight:** 200 Grams - **Material:** Resin - **Number of settings:** 5 ## Images ![100 Lap Dual Timer - Image 1](https://m.media-amazon.com/images/I/81ztX09+XHL.jpg) ## Questions & Answers **Q: Hi is this superiorly made in Japan, or disgustingly and inferiorly made in China?** A: I have 3 of them and they are all made in Japan. **Q: I am essentially looking for an easy to use, reliable, variable countdown timer.

But if you need a more intricate/high-tech watch, then this will make a great one. Just be prepared to read the instruction manual! ## Frequently Bought Together - Seiko 100 Lap Dual Timer - Zozen Measuring Wheel in Meters, Foldable Meters Measure Wheel | Metric Units [Up to 9,999m], Rolling Measurement with Backbag, One Key to Reset/Kickstand to Keep Stand/Starting Point Arrow. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/12588287-100-lap-dual-timer](https://www.desertcart.be/products/12588287-100-lap-dual-timer) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-05-03*
