This time round I handled the Seiko Prospex SBEX009, a 62MAS reissue that commemorates the 55th Anniversary of Seiko dive watches. Seiko actually released two of these 62MAS reissue models this year using their 8L35 and 8L55 movements respectively. I posted the 8L35 model (SLA043J1) on this blog a few weeks ago. (Link provided at the end of this post)
The model featured in this post is powered by the 8L55 movement which is a high-beat (36000bph) movement. By comparing the specifications of the two watches on Seiko’s website, I notice that the 8L55 movement has a power reserve of 55 hours which is 5 hours more than the 8L35 movement. The SBEX009 is also 0.6mm thicker than the SLA043J1.
You can tell the two watches apart by looking at their second hands. The SLA043J1 has a blue second hand while the high-beat SBEX009 has a silver coloured one. The SBEX009 has the word “Hi-Beat” printed on its dial right under the Seiko logo. In addition, the SLA043J1 comes with a waffle style silicone strap while the SBEX009 comes with a Tropic silicone strap.
Below are some pictures of the SBEX009.
