This is the latest generation of what is Seiko's most famous and most capable dive watch series: the Marine Master 300. It is powered by the 8L35 movement, being assembled and finished in a Grand Seiko factory. Time keeping is excellent and within COSC limits. All operational aspects are perfect, including bezel alignment. The exterior is in excellent condition with very few signs of use. There is a tiny ding on the edge of the bezel at the 30 minute marker, you have to be looking for it to notice. The clasp of the bracelet has three hairline marks on it as well, these can be easily brushed out. The bracelet has all of the original links and it will fit up to a ~8" wrist comfortably. It includes a Seiko box and unfilled warranty card dated to Nov 2022, so it still has warranty. All in all this is an awesome dive watch that has a two decade long track record of proven performance. **Other posts**: **Other posts**:[Breguet Type XXI Rose Gold](https://reddit.com/r/Watchexchange/comments/1ban6iv/wts_breguet_type_xxi_42mm_pilot_chronograph_18k/) - [NOMOS Zurich Worldtime](https://reddit.com/r/Watchexchange/comments/1ban2xq/wts_nomos_zurich_worldtime_midnight_blue_40mm_ref/) - [Tudor BB41 S&G](https://reddit.com/r/Watchexchange/comments/1banf1o/wts_tudor_black_bay_41_sg_inhouse_cosc_2145/) - [Tudor BB41 Blue](https://reddit.com/r/Watchexchange/comments/1ban5dz/wts_tudor_black_bay_41_blue_ref_79540_on_black/) - [Chopard Mille Miglie Jacky Ickx LE](https://reddit.com/r/Watchexchange/comments/1banacl/wts_chopard_mille_miglia_le_jacky_ickx_42mm/) - [Doxa 300T Forged Carbon](https://reddit.com/r/Watchexchange/comments/1banccm/wts_doxa_sub_300_diving_star_cosc_forged_carbon/) - [Chopard MM GMT Panda](https://reddit.com/r/Watchexchange/comments/1bandp8/wts_chopard_mille_miglia_gmt_chronograph_le_panda/) - [Omega Seamaster 300 LE AC](https://reddit.com/r/Watchexchange/comments/1banqyt/wts_omega_seamaster_americas_cup_18k_wg_bezel/) -
